Odd Bishop bug
For some reason Bishop is going into overload when he's under 30 prowess charges. I've been able to recreate the bug consistently, it happens when the prowess is used to heal rather than for special attack damage as if the game continued to count them up past 30 even if the visual number was under. The only way I found to reset this is by using a special attack, after which the overload degeneration would stop.
