Well, I‘d say it really depends on how mechanics works in the background. If JTR just checks if she is debuffed by a skill at a specific point it would be a 40% chance to cleanse it all (which I assume is the case; reason later)
If she would check for EVERY instance of debuffs it would be - in the case given of 2 debuffs hitting her- 2 times a 40% chance.
I guess, as stated above, that one ability that debuffs her makes her check 1 time at 40% whether she cancels all debuffs or not. Otherwise it would probably make for weird mechanics and calculations ingame.
So a Vaders uses Force Crush and would apply 3 dots. What happens if EVERY instance of the debuff would be checked? She could end up with 3 dots, 2 dots or 1 dot depending on RNG. So I‘d say it is either all 3 being canceled or none.
Thus, I believe that JTR checks once per ability (basically once everything of that ability has been calculated; no matter if it would leave her with 1, 2 or 100 debuffs) whether all debuffs are canceled or not at a 40% chance (I‘d assume it to be the same, if an ability would debuff her AND trigger a unique which would debuff her. All instances of this effect and aftermaths are calculated before the 40% chance is applied)
Another different question comes to mind. How does lead Zader‘s Force Crush work on her? (I haven‘t been in that situation yet).
Is there a loop in the background until the dots are applied (because theoretically she could cancel them infinitely, while Zader would apply them infinitely...?)
