sp3, he makes the opponent hit themselves
that would be epic
How about Debuff Reversal as a mechanic? Any Debuffs the Opponent would apply on Kilgrave have a chance to be applied on the Opponent instead?
There'd need to be a way to negate it, eg ability is paused for 10 seconds after getting Knocked Down, reducing the reflected Debuff's Potency by 50%, or something.
Maybe he'd cause Miss as well. After all, he wouldn't want you to hit him, and you wouldn't want to do something he asked you not to do...
