I'm not sure if this is a balancing mechanic or a bug, so I was hoping someone could give me a second opinion. In one of my games I could use it as often as I wanted no problem, but in my current game my character is able to "resist" the skill and then it won't work, like I'm resisting an enemy spell or a curse. Is that a bug or is that the game balancing it somehow to prevent me from exploiting it and I was simply lucky last time? Also, my character is resisting it even if I haven't used it in a few hundred turns.
It is a bug, right now all dots can be resisted regardless of whether they're beneficial or not (and the regeneration effect of that is implemented as a dot)
