Fucking hell at that Black Hole stuff.
The most troll aspect of the hole thing is the goddamned HP - debuff falling off halfway through the White Hole cast. We went through a few iterations of positioning and pathing (i have my fingerpaint drawings somewhere) but once you get it worked out you feel like a badass taking deadly tight turns around stationary holes and I kind of like the sequence now? There's enough RNG to it that it feels like on-the-fly decisionmaking and it's rewarding to get consistently down.
but seriously fuck that hp- I always forget it's going to do that.
