The ONLY video you need to Conquer IS4 

I know it's lengthy but stick with it and it'll get good. Trust. 😊 You can even watch this while eating or just listen to it. Also I forgot to add on the video that this is all recorded on Base difficulty. I mostly want to cater to new and mid game players. I'm sorry if you expected high tier gameplays.

Integrated Strategies is probably the biggest contribution to my accelerated growth on Arknights. Just started last year and can now consistently clear story and events with Low Rarity Operators, 6 Stars just do what Low Stars do but faster or in a unique way, and even then, Low Stars have their own quirks that give them a little oomph. Which is why I like Arknights for what it is, don't really need to desperately chase new operators for the next meta as you can generally clear most content without the best of the best (excluding DoS) Integrated strategies, specifically IS3 (the one I played the most) appealed so much to me initially because it gave me temporary operators to try out. It also didn't cost me sanity, just time. Without IS, I wouldn't have learnt much about Gavial, Purestream, Gummy, Pinecone, Ethan and Pudding. With 6 Stars requiring high budget and maintenance,, it forces you to learn with Low Rarity, which is one of the main reasons many people are put off by the gamemode alongside with the RNG. And that's the thing, your squad grows with you as you learn more and more about the levels. You get to buy permanent buffs, stat boosts and different squads to suit your playstyle. Different artifacts to help with the current squad you built and it comes back full circle to learning and knowing what your Operators can do. Aside from a bit of RNG, each fight you bring your squad to will be your own choice, initial difficulty, battle nodes, special encounter nodes, it's all your own conscious decision. It's a long-run gamemode, and you're not expected to survive the first few runs. But with each failure you will learn and get stronger, which is always fun.

Currently the best IS4 guides I have ever seen. It's good for either newbies, beginner for IS, & someone who already experienced in IS But there are alot of things I want to pointed out too (if you want to experienced it yourself, you don't need to read this) - Medic & Defender is a must thing in IS4. For how much enemies that hard-hitting. Texas-Alter is not as broken as in IS3, she's still good for stalling especially in early state of the stage, but I prefer Kirin R Yato who deals a ton of damage - You forgot to talk about the Cross-Cultural Comparison/skills tree. It is a pretty impactful thing in all of IS. Make sure, to upgrade the point that will allow you to *refresh Rogue Trader for each encounter* , *gains additional Foldartals choice after battle* , & *gains 1 Anti-Interference Index upon entering floor 3* And if you're wondering what to upgrade, just make sure to follow the enemies buff. For example: in Diff-7, the enemies gain 10% DEF, so you need to upgrade the ATK point - Diff-7 is when things starts really hard. Diff-10 (for medals) is easier than IS3. But Diff-11 above is hell - The META starter squad here is Reed-Alter, Orchid, & Popukar. Because their abilities are so useful in Floor 1 & 2. You can build your roaster at the end of floor 2 - floor 4 - In floor 1, take as much battle as you could since the difference between 3 battles & 4 battles is huge. Take the Emergency too since it's not that hard. It will gives you a ton of resources 28:28 avoid the emergency version of this stage at all cost if you don't have Typhon. Buldozer will appear here, & the stun sniper here deals a ton of damage 33:50 other way to link the laser effectively is by deploying an operator (especially vanguards) at the top left corner. Yes, that caster will attack them. So you can use Fast-Redeploy (Kirin Yato S3 is the best here) to kill them And you don't need to worry about the first few mechs that appeared from red box, just build your DP first to immediately deploy your laneholder & medic 37:10 if you happen to have Mlynar, his taunt is really helpful here. You can build your defense & not to worry about that binds attack (that deals alot of damage) 38:07 funnily enough, Popukar + Mlynar is enough to deal with the left side (just to make sure to deploy Mlynar beside that Reed-Alter tiles, because that way he can damage the boss & "Crowd-Controling" the left side) 38:14 if you looking for replacement, Mudrock + range damage dealer (especially Reed-Alter) is enough to deal with it 41:05 someone said that it's actually for every 30% HP lost, not 25% (so it's 70%, 40%, & 10%). Debatable, but still not change the way to beat the boss 42:16 because of the fact that the boss will explode a freeze effect everytime he stops running, the best tiles to put Medic are: - Stall 1: Eyja-Alter or Pith tiles - Stall 2: Ansel's tiles, facing left - Stall 3: Above Ansel's tiles (facing up), or that EB's smoke tiles above Typhon (facing left) - Final stand: Ansel's tiles, or that EB's smoke tiles above Typhon (facing down) Also, in ED2 you don't need to bring boss-killer. You only need to bring range lane-holder or crowd-clearing operator (well 2 of them is Mlynar & Chen-Alter lol). Just reduce the boss HP little by little Btw, you can pass that first running-lizard & the drones. Just make sure you generate enough DP to build the main defense line 45:08 - keep in mind, this boss has 2 phases. So don't be surprised if it's not defeated yet, because you're still in phase 1 - this boss may appear flying, but ground operators can still hit it

For ending 2 boss you can pronounce his name like this = (Ache-Turn-Ear), it is based on the name of a type of deer in Norse Mythology

You weren't kidding when you said this would be a mega project, haha. One helpful tip for the Bosky Passage effect: In case you miss it the first time, you can go back to the main menu and re-enter IS4; this time, the screen displaying the effect will stay on until your next input.

FYI: E1 70 Pluma can solo every non emergency stage on floor 1 with a well timed S2 activation. She can handle Beasts Awaiting Slaughter, Hands of Moss, and Ghosts of the Resort as emergency ops with some basic help. I recommend skipping emergency Prisoners' Night if you don't have a good way to kill the brawlers quickly.

One way to check the Bosky modifier is to quit the IS stage and load back in. The loading page for the map (bosky) will be shown until you click once. 25:20

Reed Alter is the MVP of this IS. Pair her with Popukar for the first floor and all emergency ops are easy af. I do notice that she falls of into later floors though so it's good to have a 2nd healer. And save the Sing foldartal for the final boss. I didn't or probably missed it, but foldartals stack based on my experience.

this guide helped me start out w is4, thank u so much!! i was def overwhelmed at first. i wish there was similarly well-organized, thoughtful, and clear content for is3 😢

Holy cow this is the best guide I’ve seen so for. A lot of others just briefly explain the new mechanics and that’s it, but you explaining each stage type is super helpful :)

Very encyclopedic video, the editing is actually very engaging and kept my attention occupied, good job👍

Great video. I was expecting you were going to go into details about team comp and recruit choice but I guess explaining every stage also works

Thanks for the video, this is afaik, the most comprehensive IS#4 guide up to date.

Just a wee something for Ending 3 boss : This thing teleport based on time ( about 20 sec per move on phase one and much faster in phase 2 , but does kinda fast teleport a few times randomly only in phase 2). Medics are absolutely needed, the best choice would be eyjaflalla alter , but best if you have 2. DPS best choice is Typhon since S3 can track the boss and fire as soon as you activate the device. Recommend some sniper relics to increase dmg and speed for maximum pain. For ending 2 , if you struggle with holding this stud ( pun intended ) , he is not immune to MOVEMENT SPEED DECREASE. Use miss Mostima S3 (preferably with her module ) for 90% movement speed decrease. Adding Saria S3 , the boss could not even move , let alone attack , but without Mostima or Saria , you can use Istina or any operator that will decrease movement speed ( do notice that not every decel binder does this, so read carefully if they actually does the thing you want them to do ) . No need for DPS ( if you want to make your life difficult ) but do bring a few stalling ops . Using this strategy , the boss most likely wont make it to the last section , putting more pressure on your last line of defense , and dont let him make it to the last line with one more sprint ( a lesson well learnt after the moment of illiteracy ) , you most likely wont be able to redeploy anyone fast enough to slow or stop him. Great vid tho for new players on the path of pain that is grinding this mode, the thing with snek woman stalling the boss was cool , def would try if i had any sanity left

Devil's number subscriber here. Will listen to your tips and insights on IS4; been wanting to rekindle my passion for Arknights for awhile, and this is shaping up to be a primer for IS4. Many thanks!

Yo as someone who has continuously maxed out the IS modes, this video was quite interesting. I watched it for entertainment but since I haven't encountered some alternative forms yet, this was also quite insightful in that regard. Keep it up!

things in this video I would pick apart. Foldartals: the ones that appear orange are red. Did a bunch of runs thinking I needed to pair orange with orange, but apparently they just are red with some colorful decals making them appear orange. also there are a few really powerful foldartal combos. the one that spawns a bosky node and sets adds +6 index when you visit the node. the one that adds an extra combat related artifact when you visit the node. and Yes I suppose 'select all non-combat nodes, change to emergency ops, select all combat nodes add one combat related relic. gives you....a floor 4 that gives you a pretty sweet amount of relics and XP. if you get the artifact that increases your index cap, and the foldartal that spawns bosky nodes and the folderal that 'select one node and all nodes connected to that node. you can create a bosky area where you can visit 3-7 bosky nodes and each give you 6 index + whatever index you find inside the bosky node. I think the highest I've ended a run with so far is 24 index which is 144% buff to attack and HP for all your guys. and that was just with two good bosky nodes. and a run that wanted to give me index.

I cleared ending 2 last week, so getting ready to challenge ending 3. I love IS a lot, such a fun gamemode. Great detailed video, should be very helpful to people

40:00 You can also use mostima to make sure he doesnt get too far, Mostima decreases enemy movement speed rather than slow debuff so nothing is immune to her slow.

Great video! Thank you.

Thank you I have complete IS2 and 3, when i start is4 i found that it was so hard, it was totally different compare to is2 and 3, your video help me a lot. you earn a sub.

Thanks for the previews, i went into ending 2 boss blind and was taken by surprise by how he just deadass run through my defenses, just managed to cleared ending 2 today.

Funny enough, I was searching for gameplay guide for IS-4 in world of tank, but this will do too

Thxs...gonna study this video when I got the time

I liked IS 2 and beat it many times, but IS 4 has been the most frustrating system ever in the game for me. I think they just make each new IS more complex and power creeped than the last one to accommodate the end game players. I can't imagine any newish players having any idea what's going on at this point.

really really good guide overall especially since you break down each possible node by the floor i think you only missed one crucial thing, the difference between emergency and normal stages like with more enemies, different spawn,different pathing etc since sometimes it could be make or break if its your first few attempt and sometimes could end the run.

That's a really helpful video. I sleep too much on Reed Alter, I should try using her more. I've also been using Dorothy a bunch and she works super well as a damage dealer, especially with ranged tiles being so limited in many stages, so she can reach the entire map easily

… did… did I just spend 47 minutes watching guide about IS4? 😂 Honestly, it sheds some light on this accursed mode I've been struggling to clear. My utmost gratitude to you.

some correction on the boss infos, for sami, it doesnt bind ops on random, it binds the last deployed operator, last 2 deployed if below half hp, for emo boi, its every 30% hp lost, not 25% hp lost, good vid

Musical disaster gets interesting if you put a unit on the top left corner facing right. That will "beam up" all the tiles and allow to gain SP normally. But violin jerks become dangerous, their damage propagates through the beam.

Great guide, thank you! Have you thought about doing an additional guide for when new combat nodes are added? I would ask for IS2&3 guides as well, but I suppose the demand is probably lower since they are older content now.

Extra Tidbit on Musical Director. Have a cheap robot unit or any unit of choice deploy them on the Top left corner facing right. It will tune every all of the tiles. You will have ample amount of time that the non Mechs mobs will move

Thanks for information

Thank you

Thanks

Oh man. I need another of this video on IS3😅😅

you are a gem renegade. subbed. salamat.

You can also silence the hovering boys. It’s quite fun to see them hovering above holes just to be silenced by Lappland 😂

Sorry mate I'll just leave one more comment on ya, There's one that'll sound very negative so I hope I don't come off as a hater but I really hope you won't take it as criticism but I really do think they help a lot in regards to the early game: Prisoner's night: if the 1st rock is destroyed some prisoner actually walk into the holes, so you don't want to surround the 1st rock with rangeless melee Ops too quick Beast to the slaughter is the reason why KirinxYato is preferred as a starter instead of texas, Yato s2 can burst the sheeps without it running past you reliably, also she can kill invisible treasure dog without being stunned due to how her s2 works. Don't turn around sluggies, the tile 1 right on where ines is deployed can actually block everyone on the stage, sometimes the game just doesn't give you enough melee unit vouchers and people who starts with kalsit or jessicat uses it to great effect. if you have two or more blockers the video does show more optimal blocking setup Low-altitude maneuvering: try and put your best dps ground unit directly above perfumer tile, facing right for the extra attack boost from air vents. Unwell: DragonGJY has a great video on it detailing the other different exploitable gimmicks, i am just lazy to type it lol Rock and a hard place: if you have ines two tiles up where jessicat is, facing right to start stage she can solo hold the right lane whilst getting early DP, they just sit there for a while Rational Fracture: one laneholder where cantabile is and one laneholder two tiles down, one left of cantabile can hold all the enemies. the elite enemies from top walks all the way down first and then goes into nearl's blue box and mobs from bottom only goes to cantabile's blue box, caster go to all the way right so two is all you need. New Tribe: A good Aoe healer with good enough laneholders can just solve the stage if you don't have typhon or can deploy her in-time. the boss doesn't do much dmg by herself so leaving her last is fine. casters to deal with the parked rocketships since rocketship hurts and eats 3 block. These two late-game stages are really big red flags in your videos I think: Company Entanglement: The emergency node spawns 3-block only running mobs. and occasional stun snipers will spawn at the start in the bottom undeployable lane. I know your stage didn't have them but the emergency version is very game-ending if you don't have enough defenders and dps and deployment order in place Instinct contamination: The emergency node makes nearl's tile un-deployable

Hey this was super helpful! I wasn't able to watch the whole video, as I'm only up to floor 3 and didn't want to spoil, but I was wondering if you would to sample runs?

Thanks, as player who dont play IS4 yet i need this

There's also a second way to stall the ending 2 boss, by using Mostima S3modlv3 (since the boss is not immune to movement speed slow but is immune to sluggish slow) or Qanipalaat S2 the moment he tries to run (not levitation immune), you essentially can waste his self-destruction by making him unable to run 1 tile at all and be blocked by the same defender at the end once again

I'll put this comment down seperately, since I can't currently find any other good guides teaching players how to clear IS4 optimally apart from DragonGJY's video, so just treat me as another passionate IS player hoping to spread more ideas and love in the yt side :); If this video is intended for new players, I think you should explain the squad selection part, the extra starting bonus of kettle relic etc. And Ideal squad starting vouchers to pick, or plan to cover it in your next video. I'm sure you knew already but Jessicat for defender start or reedAlter for support+medic is most stable, ling on Braving3 or lower or a KirinxYato/Ines start for Vanguard+specialist. Matching same coloured fordartals (i just call em top/bottom stickers) also reduces collaspe value by 1, the 'cycle' flair just decrease the collaspe value by extra 1. When you want to re-read bosky conditions just exit to IS4 main-menu (the wallpaper menu) and enter back, the loading screen will pop-up again. Partial Cecity is a rare collaspe value debuff, it doesn't come up on the menu until you encounter it, but it blurs your life points and on stages in blurs the enemy and your operators health if you wanna do more videos on is4 might I suggest even a tierlist of ops to bring, or relics, or foldartals? those are always cool.

私は Google 翻訳を使用していますが、アークナイツには最高のガイドがいくつかあると言いたかったのです。ご苦労様でした。! :)

If you want to read the bosky passage description, just go back to is4 main screen and re-enter the journey. You can read the description slowly.

Lets go

Can u do a video on SSS modes?

14:20 Yato Alter S2 does not get stunned immediately and can cycle full skill to kill it xD

IS in general is really hard if you dont have enough units with at least some levels :(

Maybe you should add the additional enemies from ed3 and emergency battle. Some are tricky to deal.

This video single-handedly sold me into getting Reed alter lol

Being Typhoon-less at BN15 is such a pain.

Regarding ending 2, it's a "free boss" until certain Diffs, relicless, which operators can reliably tank the boss at Diff12?

You missed a Collapse Paradigm. It obscures your info such as your current HP, Max HP, Objective Shield and Hope/Max Hope. Plus it prevents you from seeing enemy HP bars

I'm very curious what difficulty you're playing on. Some of these tips don't apply at D15 (e.g. Collapsal's Afternoon is by far the scariest F4 stage unless specifically drafted against, it's arguably easier to let the very first box be broken in Defense Substituting Offense to create a small kill zone). Also, I'm pretty sure you're missing a good amount of info, such as Instinct Contamination Emergency banning the tile in front of the blue box.

how am I on floor 6 without getting the Routeweaver Net.. I also have 3 prophecy nodes at the end of the floor

I forgot in previous comment : thanks you for this guide. I come back to Arknights recently (i pause few weeks after IS3 start), and i feeled completely lost and bad on this IS4 (most of the time : loose on floor 2, sometimes lost on floor 3 boss). This + best operator for IS4 videos helps ma a lot (Reed carry me) :) Edit : at 1:29 you mention that you'll show how to get 1k5 points. I don't find the moment you explain it, when it is please ?

Wasn’t there also some super rare pardigms? Like the one where it hides your hp count so you have so leaking enemies is a huge risk

thank you for making this video, i realy apreciated it, not because it helps me in is4, but because it shows me i will NEVER be able to complete

I have a question, not sure how many noticed this but...when you select which squad buff you use at the start of the run, you can see what endings you have cleared with that squad, but the thing is...some of the ending's symbols are shaded, some are clear and bright...what's the difference and why? IS 2 and 3 don't seem to have it

33:49 One Mistake on this Fucking stage, and its end of my Run First Mistake: Putting my Kal on the Bottom High Ground on the Right, Somehow....

I don't find Terminus of Life that bad since you can spawn kill the boss and most of the mobs from the middle/bottom spawners with Typhon S2 on that middle island. Wandering Medic facing right on that middle section next to vent, Typhon below them facing left.

"Penalty" also has *very* slow DP generation rate, so prepare your vanguard

Can you do the other IS? and also, what do you suggest to play first if i didn't play all 3 IS? (Yes, i play Ceobe Fungimist but never completed any ED, only for points)

Any advice on how to replace Typhon on Floor 3 boss (i don't have GG too :'( )

37:21 NUKING SAMI'S WILL WITH MUMU??? WTF?! IS IT POSSIBLE?!

Why is this game mode so hard, I only got up to floor 3 so far. Died to the stage with the flying rock monsters. What am I supposed to do like bro, guess I’m forced to build 4 stars before I can continue

PLEASE WHAT IS THE SONG AT 27:30 I RECOGNISE IT BUT I FORGOT

Just wanted to say that the challenge version of the 19:18 stage is just bullshit, every time I see this emergency stage I just restart my run cuz movement speed and damage buffs are too insane to deal with at the very beginning of the level and if you failed to deal with it - you probably won't be able to deal with the entire stage. My personal nightmare of bosky passages...

Is4 surely love drop black smokes on every run

Now make for is2

Understood, *goes on to fail ending 2 boss for the third time*

I Facing Eikthynyr In Difficulty 11 and HOLY FUCK HE'S MURDER MY SKADI TOO FAST (Without Survivability Collectibles BTW)......

So what 4 and 5*s are good for IS4?

So I gotta pray for 6-star temp recruitments 😔

9:45 What "Easy and AFK-able" when i use Typhon as a Starter....

guys I didnt even finish IS2, how cooked am I?

Walmart FrostNova💀

guys, don't rob cannot, he shit on you big time

1. In *Unwell* , you can and should break the boxes for more starting DP if you have at least 2 ground ops and 1 ranged op with 3x4 range or bigger (AA snipers, medic). Place that ranged op on the tile to the left of Hibiscus to scan enemies and you don't need chokepoint at all. 2. *Do not* rob Cannot on ANY floor. He casts buffs more frequenntly now and the undying armorless assassins with massively buffed aspd will clear your board in a couple of seconds. 3. *Do not touch Altar of Craving emergency* if you don't have an E2 high lvl AoE medic. Better yet, *do not touch Altar of Craving emergency* at all. Repeat this a third time if necessary. 4. *Typhon S3* can nuke all floor 3 bosses in one activation up until difficulty 10-12. 5. In *Defense substituting offense* , you should let the hammer bro destroy the first roadblock and stop him right after that. Also set up a focused DPS zone around that. Every hammer bro will follow that exact same path. It's much easier than trying to block them before the first roadblock. 6. In *Musical disaster* , you only need 1 op (preferably healing defender) facing right on the top left corner. This makes the laser pass through every enemy unit making them (especially golems) much easier to kill. Try to kill the left side casters ASAP.

I most of the time...got black lung cancer smoke debuff💀

I know why i suck, cuz i don't have typhon

Something I dislike about this guide is: here's a guide to mini bosses: use Typhon instead of showing strategies with other 6 stars and below..

Out of all guys who ask for a sub and show a percentage you got the worst ratio, oof 98% unsubbed 😂

aint no fuckin way you use THE song at the start 😭😭

This guide is not very useful bc i don't have Typhon
