Bugtested one of the endgame bosses -- the second-to-last one -- and rebalanced its hidden "rank" mechanic, which a few bosses have (especially the Lightside Kris fight in North Edge, which this boss is very similar to and shares a lot of code with) to increase its speed and damage whenever its attack patterns loop around or it falls below particular HP thresholds. It's pretty good now, although I feel like it's a bit damage spongey, I might change that later.
