A setup to time the nail hit instantly when Trobbio pops up at the start. Pay attention to the pair of spotlights swinging back and forth in the background starting after the dialogue. Just after they settle on the middle and have stopped moving you start to attack and the 3rd nail will hit. Regarding the position you stand in, the spot used in the video is far enough left to not automatically get you hit if you mistime the nail. This is close to the furthest left you could be while still being close enough to land the nail but there's a little leeway. Much further right and you will get hit if the nail doesn't push him away pretty much instantly.
Consistent opener for spawning the 2nd moss mother instantly with just n1 and spear. You just jump and attack, turnaround spear, and then dash and attack once more. The important part is that these 3 hits need to be done before she smashes her head into the ceiling, as it seems she will always spawn the other mother when doing that move so long as enough damage has been taken. Video example of doing this 10+ times in a row https://youtu.be/h0c3jwccFNQ
these first 3 attacks can be forced and leaves her on 3 hits from staggering. if she doesnt do the 2nd jump attack its because you werent in the air for long enough. you can also choose to send the 2nd jump attack to the left but its generally harder to hit her i think. if she backsteps after the 1st attack you were too slow
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
