Hi, my friend went on boss the champion in act 6.2.6 with stealth spiderman 5* rank 5 aplicate slow debuff on champion and he were still unstoppable, how is that possible? He tryed that many times and spent a lot of units for nothing, becouse he could't take him down.

Use the search tool, this is about the millionth thread on this. Champion has increased ability accuracy which means he can still gain unstoppable

If ability accuracy increases the chance of Unstoppable activating to above 100%, it can still activate while Slow is applied. That said, Slow will still cause the affected character to react to every hit as though they weren't Unstoppable, even if Unstoppable is up. We're working on getting the description updated to reflect this.
