South Park Fractured but Whole Final Battle Diabolical No Damage

This fight is fucking insane. For the longest time I figured it was just random chaos and them using cheat abilities so I never bothered to actually figure out what was going on. Basically, the first three phases there's only one you need to kill. The one you need to kill will ignore you and focus on the other and the other will attack you, ignore (most) status effects, and redirect any damage, with each phase conditions getting worse if the other were to get hit, from phase 1 he simply redirects damage, 2 where he swaps places and redirects, and phase 3 where he puts a status effect on everyone. So how the hell do we control his untouchable monster coming for us? Old fashion AI abuse. While we can't directly enrage them, every enemy in Fractured but Whole has a simple thought process when attacking, attack the nearest available enemy, while prioritizing multi hit attacks. This process will even ignore confusion telling them to attack the nearest enemy. How we use this in this fight is use our skipped turn while we are shielded to drop ourselves in a straight line along with an in air Mintberry Crunch in order to trick Kyle and Cartman to dash at immune characters. But that's only survival, how are we actually killing these guys? Allies basically need to just keep out of the way while Butthole deals with the entire fight. We need a very specific damage threshold where we can set Cartman to die on his turn with Bleed but also kill them when needed, that's why you see me messing with artifact at the beginning of the video, the 125 might merit badge actually just barely makes you deal too much damage. But why do we need to kill cartman on his turn with bleed? The aggressor always gets the first turn on each phase UNLESS they die on their turn on the previous phase, in which case Butthole gets the first turn no matter what and the aggressor's turn gets pushed to the back. This is how we can come into phase 2 and 4 untouched. We do enough damage at this point where when they stop cheating, we can easily kill them before they can get a turn. And with that, we've done the entire main story, we still have Morgan Freeman but I'll bundle him with one of the DLC videos since he's one of the easier fights once you have him figured out.
