Well, I don't use any abilities that do that and I keep loosing more Health every game. If this is a glitch please fix it Krin and this is the main topic the other one was glitched somehow.
If your phycological then that will happen... im pretty sure it's because... well your phycological and I guess it said you are part evil or something but sometimes you get healed instead of getting hurt... This happens with my phyco character... don't worry about it...
Another possibility is that a certain skill does that on purpose... phyco skills are like that...
no its not a glitch, its a passive effect called overdrive, you lose 10% of ur health each turn in exchange for 10% better attacks its worthless in my opinion
