wow, it took me 2 weeks to notice that the music is p loud, prob cuz im using my own voice lol, next video will have quieter music :D Edert: I made a discord server, its in the description (check it out pls)
you can find a spot where the netherportal teleports you into a bastion, before that you get splashed with fire res, pushed around with lava (or with pistons) into a netherfortress, giving 2 extra, from there you can get pushed into another netherportal which teleports you right infront of an endportal for eyespy where you can then be pushed into it with either water or a piston for the end.
@@laviOnFirebut actually 🤓☝️u need some kinda ore to build the beacon so u can't really do the pickaxe and iron one and u will gain achievements so it will lower down
And you could drop into the stronghold for eye spy before going to the nether, and you could go back to the over world and enter the end and you could…
Could've added "A Furious Cocktail" achievement (Not to be confused with "how did we get here") by having a few dispensers splash you with every type of brew-able potion.
to abuse the rules of this "challenge", get every status effect except one BEFORE you take the shot, with the shit activating and giving you the last effect, adding 2 advancements. as others have also pointed out, a nether spawn in a bastion or fortress grants another achievement, but we can take this further by visiting 4 nether biomes beforehand, with the nether entry being the remaining biome, giving another advancement.
@@AsiccAP you cant visit the other biomes though since you would have to visit the nether to do so, meaning youd just replace one achievement with another
@@cinnamoncat8950 fair enough. Then I propose the much more difficult but theoretically possible advancement of adventure time in the overworld, where I stream of water pushes you into the last biome that you have not explored yet. In addition, I believe that bullseye can be activated by redstone if I shot an arrow at a trapdoor on a target block beforehand, with the redstone activation making the arrow hit the bullseye.
Then, we replace an animal in the base with a skeleton and put it at the very back, more than 30 blocks away. That should give us the sniper duel advancement.
@@AsiccAPalso the water could push you until a string or pressure plate that activates 4 dispensers that will give you full netherite(cover me im debris)
A really fun idea would be having 2 accounts invited to an SMP, using one to set up the machine(a lot of advancements will be gotten in the process of making this), and then have the other execute it while the admin is online.
+ add nether fortress, all the potion dispensers, end room with a lit portal that you fall in is 47. You've missed 5 potential enchantments: terrible fortress, energy coctail, eye spy, "the end" and the end tab
Here are a couple more potential advancements: If you set auto sneak before you use the crossbow and here is a skulk sensor nearby, you could potentially get the sneak 100 advancements If you go the the end wearing thorns armor, if the dragon is low HP, you could kill it when it attacks. Then you could get on a flying machine to the end fortress to get the advancements: the city at the end of the game and great view from up here from shucker bullets. If you started at the top of the world, you could have also received the caves and cliffs advancement from falling all the way to the bottom of the world. If you started in a meadow and used a hopper to insert a disc into a jukebox, you may receive the advancement the sound of music. You can also have a flying machine move in the overworld in a straight line. it likely would explore every biome eventually. If the 5th mob is a skeleton, you can get the advancement sniper duel if it is 50+ blocks away. If you lock up an allay with a cake, it can give you the advancement you've got a friend in me and birthday song if a note block is played nearby. If you start in a boat and a goat is pushed into the boat, you can get the advancement whatever floats your goat. Then the boat can be destroyed by lava so that the rest of the advancements are possible.
Advancements that can also be gained: eye spy, the end?, free the end (thorns armor to kill dragon), the next generation (maybe some contraption can survive the dragon and move the egg onto a torch if dragon rng decides to be nice), remote gateway (water + trap door into it), great view from up here, the city at the end of the game (get lucky and spawn next to one after the gateway or flying machine), caves and cliffs, hero of the village(maybe? idk, depends on if you can somehow manage to kill one of them with a trident stuck in the floor or if killing them with dispensers counts, would also have to wait a long time and probably get the ai to all kill themselves), a throwaway joke, monsters hunted (line up a bunch of hostile mobs, and kill the ones you can't pierce with a bunch of tridents stuck into blocks that get moved by pistons), two birds, one arrow, sound of music (might work, idk how the achievement works exactly, i think u can put music discs into jukeboxes with redstone now, not sure), sniper duel (very easy to add), bullseye (again, very easy), you've got a friend in me, return to sender (somehow manage to reflect a fireball back at the ghast with the same arrow used to kill everything else, idk if it'd be possible but maybe), furious cocktail (potion dispensers), sneak 100 (no idea if you can keep holding sneak during all of this for it to work), the healing power of friendship, feels like home (start off the whole thing while riding a strider and shoot the arrow while riding it then drop it into a lava stream that pushes it 50+ blocks, can just kill the strider at some later point if needed, idk if it counts when not leading it with the stick but hey, it's an idea), minecraft: trial(s) edition, crafters crafting crafters, who needs rockets (might work with dispensers), blowback(same kinda problem as return to sender, idk if arrows deflect it tho), crafter might be able to complete all of the crafting advancements for you, idk tho, the last 5 can be gained by using a flying machine: adventuring time, those were the days, terrible fortress, subspace bubble, and hot tourist destinations, I might've missed something but whatever
Alright, hear me out, have the nether be an un activated portal, when you link to the nether an observer detects it starting a timer to break the portal and send you back through a different portal with its bottom half removed on the overworld dropping you into a stronghold giving you the end and eye spy.
You drop into the end, Which then sends the previously shot arrow through a tnt velocity cannon instantly killing the enderdragon getting you another achievement, which then pistons push end crystals onto the end portal giving you another achievement etc the list goes on, might as well have a teleporter setup sending you to every single biome
@@laviOnFire but can't you just hold the right click so it's still 1 input? If you start out with crossbow in off hand? Like you get shield first after your totem pops which is inside your main hand so you can use it
You can add 1. A terrible fortress with flying machine 2. Those were the days with the same principle 3. Hot tourist destination with the same principle 4. Subspace bubble with same principle 5. War pigs (I'm not sure if blowing up a nation chest answers piglins, but if so you can get it) 6. Crafters crafting crafters by being near a crafter when it creates a crafter 7. Hero of the village by going into a raid farm (you can have the effect before because killing the captain no longer gives bad omen. ) 8. Monsters hunted because you can use TNT or unleash wolves and let the mobs hurt you 9. Adventuring time using flying m machines strategically out all around the world 10. Return to sender by shooting a Trident out of a dispenser. 11. The first arrow could have gotten two birds one arrow. 12. A girl's cocktail, using dispensers 13. The end?, because you can push yourself into the portal 14. Free the end, because a friend can make a dragon killer machine that destroys all crystals, brings the dragon to 1 not range, and bubble elevator that brings you to the perch, let's you get hit (there can be healing potions at the entrance to the end), then the dog will aggro and kill the dragon. 15. Then, you fall onto a flying machine that brings you to the end city for the city at the end of the game 16. Great view from up here by being hot by a contained shulkers the that will make you feel onto a pressure plate on a flying machine to bring you back to your spawn 17. How did we get here? With a setup. 18. Way way more that I forgot.
There are so so many more achievements possible. Honestly a scary amount. Dispenser to equip armor that gives achievements (elytra, iron aemor, diamond armor, and pumpkin if that does one). Biome or structure specific advancements. And since you included the “Adventure” achievement there’s a whole tone more I don’t know that or totally possible.
I've always thought about how many advancements could be made with just one action, but haven't found any content. Props to you for figuring something out. 42 in one go is impressive.
There are even more advancements you can get doing this with commands or proper preparation: Adventuring Time) explore all biomes except 1 cave biome and 1 nether biome then fall into it Caves and cliffs) start at the top of the world and have the powder snow at the bottom Monsters hunted) optional, make sure the 4 mobs are the last monsters you need 2 birds 1 arrow) replace the 2 animals with phantoms Hero of the village) have an automatic raid farm that activates when you get Voluntary Exile, with auto killing Hot tourist destinations) have the last nether biome on the other side of the portal Subspace bubble) have a flying machine activate and take you once you enter the nether Eye spy) somehow complete the end portal without entering the stronghold ,and drop in it after getting subspace Bubble The city at the end of the game) use water to push yourself onto another flying machine upon entering the End, which would eventually take you to an End City, also completing Adventuring Time The End.. again) use a dispenser to resummon the Ender Dragon upon triggering the flying machine
these are pretty cool, i suppose the adventuring time one i missed out on, cuz i didnt really think of how that one would work 2 birds 1 arrow wont work, because the arrow has to hit 5 unique mobs, 2 phantoms wouldnt give me arbilistic the others could work but will take a while to set up, but tnx for commenting! I'll definitly put this is my future video about what advancements i missed out on
@@laviOnFire yeah, that is a whole mini series worth of content right there. Especially with the bonus challenge of not picking up any advancement-granting items. You can cheat this a little with bundles and hoppers, but I'm not sure about getting to the nether without hot stuff or ice bucket challenge. I'm trying this too, I'm just not a content creator.
well, hot tourist destinations wouldn't be possible unless theres something that can move the player to all nether biomes, as you can't explore any nether biomes without getting "we need to go deeper" in advance.
If we're going into redstone contraptions anyway, I wonder if it's theoretically possible to complete all Minecraft achievements at a single arrow shot. If not, then it's also interesting to know just how many aren't possible.
Amazing concept, this video really deserve some love :D I found it really interesting! Love to see that we can still make great content on this game after all this years!
Thank you for making this video It’s been on my mind forever on how many achievements you can possibly achieve with one action or at once I could really never think around 6 or 7
you can achive more advancements by entering into both nether stracture, a trail chamber, allay giving you an item, being pushed into a medow (and by that visiting all the biomes) to play a record, and hitting a skeleton and a bullseye with other, preloaded, fired arrows (may be considered 3 arrows tho). in the nether you can be knocked back through all 5 nether biomes and into another nether portal, dropping you in a stronghold into an end portal where you are brought closer to the ender dragon spawning, giving you 11 (or 13 considering the arrow ones) more advancements
A few ideas to raise the number: If the nether portal is in the right place and slime blocks to move you can get "Hot tourist destinations", "Those were the days" and "A terrible fortress" If you linger at the start and let a machine finish the raid you would get "Hero of the village". Dispensers with splash potions can do "Furious Cocktail". Build it over a stronghold, could add "Eye spy" and "The end (x2)" In the end slime pushers can do "Remote Gateway" "The city at the end of the game" and "great view from up here" Finally if you get VERY elaborate you can slime push yourself all around the overworld to get "Adventuring time". That's all I can think of, I'm sure the replies will think of more. (Are there more structures that give advancements? Stronghold, Fortress, Bastion, End City and Trial-Chambers-we-cannot-use-because-Bad-Omen-is-in-a-bottle-in-1.21.)
getting a bastion is def possible as an advancement (i didnt count 1.21) in 1.20.5, a few more advancements were added, so maybe some are there sniper duel and bullseye caves and cliffs if built correctly
You could replace one of the mobs with a trapped ender dragon for another advancement. If you allow glitches, you can get a multishot and piercing crossbow in 1.14.? This would let you kill many more mobs, allowing you to get achievements such as two birds one stone. If you got a ghast fireball into a stasis, you could reflect it back at the ghast for another achievement. If you get all hostile mobs into a chamber and have an arrow light a tnt above that chamber, you can get the achievement for that too. There are also other advancements you can get by being near/in something, such as eye spy, a terrible fortress, the end, the end gateway one, city at the end of the game, the levitate 50 blocks one, th e hero of the village one. If you eat all the stuff for furious cocktail right before you shoot the arrow, you could get that achievement too through dispensers and mobs activated via target block. I could see this being improved, such as starting at the top of the world in a boat, with a target block releasing a goat into your boat, destroying the boat, giving you all the effects, and sending you to the bottom of the world for caves and cliffs. It could then do the achievements you mentioned, bring you to the nether, and the bring you to all nether biomes or smth. In fact you could probably get all over world biomes too, just get all but deep dark or smth so when you fall to the bottom of the world you get the achievement. The machine could then bring you back to the overworld, into the end, into a gateway and to a city. If you fall through a meadow biome with a jukebox playing in the overworld, you can get that achievement as well.
You could shoot a ghast fireball instead of hitting it to get the "return to sender" achievement too. Ik that'd be hard but you'd get a wopping one more achievement
Next time you should make the underground stuff in a stronghold and maybe get a nether portal in either a bastion or foretress, either way this was amazing! I really like how you pulled this off, very creative and it was really cool to see ^^ Gg man, you deserve it :)
This... This is beautiful. With fire resistance splashed on you, And a lava trail, You could include Hot Tourist Locations if you happen to find a spot with all four at a reasonable intersection.
@@laviOnFire A four-way flying machine that you get automatically put into by going through the portal sounds a bit difficult, Unless you mean just going in a straight line- In which case, It would probably just take forever.
tip: add yourself at Highet limit for caves and cliffs and give yourself every potion effect then make the portal bring you to a bastion, a fortress, and do the others like the strongholdn and trial chamber in the overworld with some machine and also make a dispenser shoot an arrow at a skeleton then a target for 50 of the 122 advencements
You could get more by going back to the overworld by getting shot into a different portal by the piglin. Get eye spy, go to the end even, kill the dragon (water trap), outer islands. Theoretically you could get every advancement that doesn’t require the player to physically do something (like craft)
You could go on the kill every mob except one before, so u can get "Monsters Hunted" instead of monster hunter, which is the same amount but higher rarity
You can add potion dispensers to get the furious cocktail advancement, and add a target block way past the mobs for the bullseye advancement. Also put the below in a stronghold for eye spy
You should also spawn the wither in a obsidian box, if possible, and like make the water go for a while in the same chunk so that you get the advancement the beginning for killing the wither before entering the nether, where, btw, you could also somehow get a portal chain or smthn or ice bridge to take u to another nether portal, which puts you into the stronghold room. That’s where water makes you go into the end portal, down into the void, then traveling up a water chamber, and then down into an enter dragon killing area. After the dragon dies, you could have an observer send u into the end island portal, (by prediction) where you travel into a end city by water, up into the elytra area, and once u get in there, the water breaks the item frame. Then u get elytra!
"telemetry data" is essentially data collection, which collects data from players to "guide minecraft in a direction that is relevant to the players". a lot of people dislike the invasion of privacy, so some, like myself, install mods to disable this telemetry.
Commenting ones I didn’t see other people commenting: You’ve got a friend in me: get the allay to give you the cake or another allay to give you an item Bullseye: make the arrow hit a target block or have it be dropped on one like the do in all advancements Hero of the Village: have the pillager be the last one of a raid on a nearby village The power of books: push a chiseled bookshelf infront of a comparator Monsters Hunted: idk if this would be feasible but I could see it happening if you crammed enough mobs on low hp to get hit by the actual arrow then after the arrow hits a bullseye dropping it to hit the wither or other mobs and then using the glitch to get the Ender dragon into the overworld you can also have it hit that Edit: if you do this on the latest snapshot or when 1.21 comes out you could also add Minecraft trial(s) edition: just build above or get pushed into a trial chamber Crafters crafting crafters: self explanatory Who needs rockets: not sure about this one but I know dispensers can dispense them
okay, i wasnt clear about spawning in, it is supposed to be your first time spawning in, so monsters hunted doesnt work hero of the village, bullseye, friend in me are possible :D
All of the extra advancements I saw that could be added (or from other comments) are: All potion effects (dispensers spam potion effects) Nether Fortress (you can get pushed to one by a flying machine) Bastion (you can get pushed to one by a flying machine) Glow and Behold (if you put the crossbow in offhand and totem in main hand when totem disspears you can pick up a glow ink sack and make the sign glow) Shield Block (if you put the crossbow in offhand and totem in main hand after glow and behold you can pick up shield and start blocking piglin arrow if you hold right click) Sneak 100 (if you have auto sneak on and have a skulk sensor) Caves and Cliffs (start at the top of the world) Sound of music (do this in a meadow or loaded meadow chunk and have a hopper insert music disk) Sniper duel (Substitute one of the animals for a skeleton and make it 50+ blocks away) You've got a friend in me (Have the allay in a spot where you can pick up the items) Float on a boat with a goat (Start in a boat and have the goat be pushed into you. boat can be broken by lava or smth) Hit a bullseye on a target block from far away (make the crossbow be a glitched multishot and piercing one from 1.14 and have one of the arrows get a bulleye) Return to sender (one of the arrows from the glitched crossbow can hit a fireball back at a ghast) 2 birds 1 arrow (one of the arrows can pierce 2 phantoms before hitting the fireball) Healing power of friendship (a dispenser can dispense a bucket of axolotl which can attack a drowned in water before one of the arrows goes through lava and hits a tnt blowing up all hostile mobs except the ender dragon and getting the advancement healing power of friendship) Finishing a raid and starting one (have an auto raid farm start when you kill the pillager and get bad omen or in 1.21 have a dispenser splash bad omen potion on you) Wax On (dispense honey comb onto a copper block. this doesn't work for an axe with wax off) Adventuring Time (get all biomes except a cave one and fall into that cave one) Hot tourist destinations (get all nether biomes and spawn in the nether one you need) Subspace bubble (make a flying machine that activates once you enter the nether and takes you to a different portal) Stronghold (come out of the other portal that has no bottom bc of update suppression and drop you into a stronghold) The end (get dropped into the end portal you can get pushed by water which is off of the obsidian platform so it spreads and pushes you onto another machine) The end again (have a dispenser place a end crystal and respawn the dragon) Kill the dragon (make an ender dragon killing machine that makes it one hit and get hit while having thorns armor that you equipped earlier from a dispenser) Monsters Hunted (the tnt mentioned before blows up all hostile mobs except the ender dragon, and you kill the dragon with thorns armor) Remote Gateway (get pushed onto a flying machine that pushes you into the gateway) City at the end of the game (get pushed onto a flying machine that takes you to an end city) Great view from up here (get hit by a couple of shulkers that you could move specifically there) So that is 28 others that you could get or 70 in total If there are any more reply to me with an explanation
with prep you can get 45 with two birds with one stone (two phantoms), hot tourist destinations (all nether biomes), and a terrible fortress (nether fortress)
You could also set it up above the stronghold and fall through it to get eye spy after being dropped. Edit: forgot to mention a furious cocktail by having a target block splash a bunch of potions on you. Also in the process you'd get the bullseye achievement. Second edit: if in the first arrow shot there was a second illager (like a vindicator), this time the last part of a raid that your friend started you could also get hero of the village. Third and final edit: in the nether, you could spawn in a bastion to get "those were the days" then just a bit after that a mechanism would shoot an arrow from the overworld to activate another circuit disabling the portal and pushing you to a fortress for "a terrible fortress" finally ending in another contraption to shoot an arrow back to the overworld and send you there and pushing you to the end portal to get "the end". Maybe "the end... again" is possible in some way but idk. Okay I lied fourth edit let's go: So the achievement caves and cliffs would be possible by starting at the top, then whatever is the one where you play a disc in meadows, then adventure time and hot tourist destination if the nether part would pus you through all the biomes and in the end there was a macine to push you through all the end island biomes. A great view from up hare if a shulker was somewhere in the machine and lastly "feels like home" or the "whatever floats your goat" depending on if you start on a boat and have a goat be pushed on it or if you start on a strider and it touches lava for a little bit. Welp, here I am. A fifth edit. : "sniper duel" if a skeleton you shoot with the arrow is far away enough. That's all I can come up with. Sixth one baby: the city at the end of the game is possible and so is subspace bubble.
A few ideas but 8t would take time. You could have dispensors with potions for a furious cocktail, the nether portal can put you in a fortress or bastion for a terrible fortress of those were the days. You could then have ice with dispensors and arrows to push you to the other structure. You can then push yourself all the way to a stronghold to get eye spy. If the stronghold was far enough you could also get subspace bubble. Following this you can enter the end portal that is lit for the end... Then there could be a tnt primed waiting to kill the dragon as soon as you enter for free the end. I dont know if this next one is possible but you could dispense end crystals to resummon the dragon for the end again and then push yourself with water all the way to an end city for the city at the end of the game and great view from up here. There may be more but these are the ones I thought of.
Spawn in a fortress/bastion Shoot the middle of a target block Kill a skeleton from 50 blocks away Monsters Hunted Furious cocktail Cure a Villager (Go into an unloaded chunk) Music disc in a meadows Boots on Powder Snow Enter end (Have water break the portal, relight portal and flying machine push you into end portal) Enter end city (With piston under end portal glitch to tp you to coords same as overworld) Levitate 50 blocks
If you don't do arbalistic you can shoot two phantoms instead so you won't loose an achivement. This makes it so you can use the last level of piercing on the arrow to hit a targetblock to get bullseye. On top of this you can then move the targetblock so the arrow falls of and kills skeleton wich gives you sniper duel as long as you are 50 blocks away. You could also get caves and cliffs by falling from build height to -63. On top of this you could use an enderpearl in a stasis chamber and a shulker to get nice view from up here.
i know i missed a few and ill go over it a different video, ill definitely be using your comment in the video. sniper duel and bullseye are a few advancements that i did forget /:
1. when in the nether, you could spawn in a fortress, then knocked into a bastion, which is in another biome giving you the 3 achievement for fortress bastion and all visited nether biomes 2. in the overworld you could get 'monsters hunted' for killing every mob, aswell as getting pushed by water into another biome for the all biomes achievement 3. doing this at world height for star trader. 4. splash potioning all the effects on yourself while having the arrow make a warden spawn and all the other effects for the 2 achievements where u get all the effects 5. start in a boat, then after the arrow have a goat be pushed into your boat. 6. falling through the stronghold thats 10 extra achievements
if you fall in stronghold +1 achievment, in nether you can spawn in nether fortress +1, then piston drops you in another nether portal and it leads you to lighted up end portal where you fall and +1 achievment, also when starting machine it can throw arrow back and if you holding shield it gives you +1, +4 achievments in total possible
List of all 42 advancements (ordered as in the chat): 1. Ol' Betsy 2. It Spreads 3. Take Aim 4. Monster Hunter 5. Voluntry Exile 6. Who's the Pillager Now? 7. Uneasy Alliance 8. Arbalistic 9. Beaconator 10. Bring Home the Beacon 11. Surge Protector 12. Sticky Situation 13. Postmortal 14. Light as a Rabbit 15. Suit Up 16. Hidden in the Depths 17. Sky's the limit 18. Isn't It Irom Pick 19. Hot Stuff 20. Who is Cutting Onion? 21. Ice Bucket Challenge 22. Getting an Upgrade 23. Smells Interesting 24. Cover Me in Debris 25. Tou Need a Mint 26. The Next Generation 27. Into Fire 28.

Hired Help 38. We Need to go Deeper 39. Oh Shiny Hidden advancements: 40. Adventure 41. Nether 42. Minceraft
You could also probably add caves and cliff at the end by having a bubble column to world height than a hole to bedrock and maybe even the two effect avancments
The nether portal could spawn you in a bastion and/or fortress for War Pigs/A Terrible Fortress. And you could have the arrow shoot the dragon for Free The End. I see your getting a lot of comments with suggestions tho so I hope you end up doing this video again with as many as you can!
fear not, cuz I have already started! Also, yes, I can get a terrible fortress and those were the days which i did miss free the end i want to do without using any commands, so either in the end or a contraption moves the dragon in the machine
@@laviOnFire Ye I'm curious if its even possible, as they exit love mode relatively quickly so the timing would need to be quick. This is one of the only things I could think of that others have not commented
Can't wait for someone to actually do this in survival. I'm pretty sure you could do at least most of this with clever tricks (like trading for a diamond pickaxe to avoid getting the Diamonds! achievement, etc.)
Could you also have a contraption in the nether that pushes you through all 4 biomes and through a nether fortress and bastion, getting you those three? You could also have every potion effect applied at some point to get A Furious Cocktail, and if one of the initial mobs is a drowned or something you could have an axolotl damage it beforehand to get that one as well. Optimize this in a seed with nearby structures to get Eye Spy, or do the whole thing while sneaking near a skulk sensor to get Sneak 100. :)
to crank it up to 50 advancements you can... 1. splash yourself with every potion effect 2. hold your left click while having shield enabled so the piglin can shoot you 3, 4. spawn in overlapping bastion and fortress for 2 achievements (possible to get more achievements probably) 6, 7. Hot tourist destinations and adventuring time by travelling for a long distance with flying machines 8. monsters hunted, have one of the mobs caged inside be the last one which you need to kill to have killed all mobs
Alright so...... You missed 2 birds one stone Sniper duel furious cocktail Not today thank you Eyespy Return to sender Those were the days or Terrible fortress It spreads Caves and cliffs Sneak 100(maybe?) The healing power of friendship The sheep and cow could have been replaced with phantoms. The arrow could have been arched to go much farther and hit a skele 50 blocks away before activating a bullseye target block to start the Redstone line Furious cock tail is easily done with potions and dispensers.... If you were crouched the whole time a shield with one durability could be given to you and you block an arrow If you also allow you to be in a boat at the start you could get a goat in there at some point for another advancement I am not sure about sneak 100 as you can't sneak in water but I am sure you could somehow trigger it with enough research You could have the ghast send a fireball at you and shoot it back with your arrow (I am not sure if you can shoot a fire ball back and have the arrow continue on so you might need multi shot) for return to sender It spreads by simply having a catalyst down when the xp from the mobs drop You could have an axolotl that was in a bucket be dispensed and kill a near by mob to get healing power of friendship Then have a bubble elevator that sends you to the top of the world and wall down to the very bottom for Caves and cliffs And lastly on your way through Caves and cliffs fall through a stronghold for eye spy And finnaly land in a way to get inside of a neather portal and end up in a bastion or fortress There are some other theoretical ones like the new 1.21 ones. But in theory you have a water slide and elevator take you to every single biome. Somehow do the same in the nether by getting pushed by a mob to enter a much....slower lava slide and somehow get hot tourist destination. Terrible fortress. And finnaly end by going through a portal that gives you Subspace bubble. With enough Redstone and pre planning you could then have the portal exit to have a lit tnt that pushes you forward into an end portal getting the end?....however I doubt any of these are worth doing and would require hours of extra setup. Which brings the new total to 51 (or 52 with sneak 100)
Another achievement you cold have gotten is the one that you fall from the high limit and "mlg" at bedrock, you could built the machine in the high limit or make somehitng to send you up there
