Every phase 2 pattern killed in 4 attacks. For some of these, I'm not 100% sure if you can fully get it off before the offscreen, but I figured I'd post and let people improve upon them if they'd like to. There absolutely are optimizations to be had, or something to make them easier, because a few of these are quite difficult.
um i guess this is also possible too? i did it by accident but u can pogo dash through into a pogo instaspear as well lol not sure which is faster but to me it just looks the same
faster phase 1 kill that kills the dancer before he gets to dash to the right and ends with full silk to heal, credit to remto who i think found this or something similar
edit: upslash on the last nail hit before the first dancer attack makes it a lot easier to hit and very very viable to do consistently and in runs
i haven't seen anyone do this i think but you can usually get 2 hits with a dash nail refresh like this on dancers that are high
note that sometimes their hitbox is smaller for some reason so this won't work 100% of the time, but it usually should, for example in phase 1 on the scripted attack where the right side dancer goes high his hitbox is smaller until he telegraphs his attack (see right dancer at the end of this clip for example)
same first phase as onaku's, but with a silkspear in the end, which makes it faster but riskier, since you wont have enough silk to heal for the next phase, if you need to.
You can walldash -> wall jump to get up the scales faster! This is terrible but faster 1-2s faster than what current strat is and also cloakless so yippie
More optimized movement for Scales Puzzle room, main difference is the dash jump (At 0:10 in first vid) to skip shifting one of them. Making it up to the next platform by dashing at the right time feels consistently doable, but it seems to save time even if you ledge grab
Cogwork Dancers phase 1 and 2 makes decisions in groups of 4 moves, and there are only a limited number. Phase 1 is hardcoded to pick pattern 1C first and Phase 2 can pick from any of the options in this pool as the first sequence. Mirror options have a 50% chance to happen if that pattern is selected (excluding Phase 1 start). I've put an image showing where the location numbers correlate to, and Dancer A is the one that spawns on the right.
dont know the roomcode ill get back to this eventually:PoroSad: This opening sequence of cogwork dancers is actually entirely scripted. They will always do these first 4 moves, which is just enough time to guarentee a kill
