just an anti chain cc item idea
if hard cced for 2 seconds in past 3.5 seconds, Or if slowed for 4 seconds in past 6 seconds. you get 20% ms that decays rapidly and are immune to cc and slow for 1.5 seconds
this passive has a 15 second cooldown
would likely be for tanky champs/frontliners. that need to break free of shackles if they get caught and your team cant help you disengage/don't wish to engage.
