TotW:RM- So. In stark contrast to the rest of the game, which is a cakewalk...the final boss Widdershin, despite having the silliest villain name since Toodles, is an utter, utter, UTTER bitch as a boss. He tears through your PCs as if they were tissue paper (not that that's hard, since you can't, you know, give them any sort of equipment), his moves have stupidly large hitboxes on them, and he does about, oh, three or four times the damage of any other boss in the game. Per hit. Mrf. His pattern is pretty easy, it's just also very easy to get caught in a death combo, which is maybe one or two moves depending on what he decides to use. Luckily he has some bad ones/easy to dodge ones that he uses pretty often to lessen those odds, but... mrf.
I think it's like a point some angry programmer wanted to make to his boss. "Hey, you know those minor flaws in the game you said wouldn't matter? Let's magnify them 100x for the final boss and see who is right."
