Also it's strange that Deathsinger is the only phase that doesn't end immediately after killing her. What exactly is the trigger to ending it? Killing the knights?
I still don't know which is dumb when you want to set new speed run times. Like sometimes it gives the checkpoint really fast and other times it's slow. We think it's timed but then again I timed it like 30 times so far with a stop watch after killing the deathsinger and it always has been a different time.
There is a set pattern for let's say the yellow knights coming out of the door in the middle room though. It is always 4 sets of 2 knights coming out of there so maybe it has to do with killing a certain number of yellow knights.
