This is still severely bugged. It says whenever a poison fails to inflict, they gain unstoppable but that's not how it functions. I used Sparky and just built up poise charges, not hitting them or getting hit, and the enemy AI kept gaining Unstoppable, and as soon as it wore off, it would immediately trigger again, still not making contact with them. My champs are dropping like flies over this. And leave it to Kabam to offer the players a "boost" for BS unavoidable damage, then add something like Unstoppable, then release it completely bugged. It's pathetic. I'm losing resources over this shite.
