Update: got to 186 before the game crashed. Modified version of the strategy using the Stinger with Shattered Aspect to pick up both Dragoon and Paladin and a bunch of Shelters to keep the stats pumping up. Random damage fails against Lonely Witch but regular damage is sufficient to keep going, though it takes a while to chip through the massive health bars. The build would probably have eventually failed against Black Knights spawning too far in the hand and halving health enough times that regular attacks could chip through it, but I think it would have managed to get to 250 or so if the game hadn't crashed.
