so there are 3 platform breaks... the first one youre probably ok with... just hang around the middle/bottom and then go up as she starts to tar the stage. circle around the top dragging all the skulls behind you (you need move speeds on boots AND amu to outrun them, so if you dont have this then find items to swap to for this part). then for the second top right break this is the tricky one - as there's often a blister on this platform. The way to get around this is to approach the right and once on the platform (you need to wait for the tar before getting there of course) pop your smoke grenade... this makes you run faster and you cant be slowed if youre too close to a blister. Skulls will also not target you (but will still kill you if you accidentally run into them). for the third platform break its more run around and the skulls tend to be fairly bunched up, so when you get on the platform run along it and then (while staying on the platform) dodge the other way. this will give you tons of time to then leave the platform. This platform is also tricky because it's small so you tend to accidentally leave it too fast and end up in the flames. Dodge will help with this. Even after this she can shoot skulls it seems, so only shoot at lilith for the final kill when youre clear of them. good luck!
