Auto pot does not work, for me, I've tried all different settings, and even buying a new pet, but nothing has worked. As soon as krex's first eye had died, i was unable to hit the 2nd eye and was not taking any damage from it either(tested by standing on the eye and not dying). Nothing worked, tried un-equipping and re-equipping, all different standing spots. and nothing.
Alright, I'm going to try this now and see how it goes. Update #1: Seemed to fix pet issue with auto pots, unsure with Krex as it's hard to find a party to go there.
