1.4.4+ speedrun, glitched, unseeded, moon lord hell yeah decided to do a couple runs of this, and i got this time! not quite a sub 20 minutes unfortunately, but still reasonably good run.
Simply put, she used a glitch that transmutes and spawns items And by that she spawned the necessary items to power through the game, and the only hard work involved afterwards required finding a Plantera bulb
i glitch to get specific endgame gear, zenith, terraspark boots, soaring insignia, celestial starboard, solar armour, rod of harmony, endless shimmer bucket. i also get a few game progression items such as the golem altar and cell, celestial sigil, mechdusa spawn
Its an easy glitch execution wise but its so complex to understand it makes it hard to do anyway, basically coding the game in the game messing with the sprite sheet, like zelda wrong warps
During the 5 first minuts I was like "mmm'kay everything seems to be normal, how could you manage to reach the Moon Lord in less than... a few days lol". And then : OK bro...
i have a couple tutorials on my channel, but the bug that makes all the items spawn is called "mCGO" or multiplayer campfire glitch offset. find Ethyriel Y's video on transmutation for an explaination
no, i usually just use that forst hill cave to get a little extra loot (goal is spear + 4 iron bars + glowsticks) and secure the location of at least one pressure plate. learning the dead mans chest setup would probably be useful though lmao
