Beating the Fourth Chorus in Hollow Knight: Silksong requires you to put on your thinking cap, though admittedly only at a jaunty angle. This is the first boss you'll face in Silksong that actually has a bit of a gimmick, and you'll have to do something very specific to conclude the fight.
It doesn't help that he constantly smashes the platform you're standing on so you fall into the lava. If you haven't reached this point yet or got the Drifter's Cloak, you'll need to find some Hokers before you can escape the Far Fields. You'll actually need that upgrade in this fight, plus it's the only way you can reach this boss on the way out of the area anyway.
