Every 5 seconds the next Stun, Bleed, Poison, Shock, Incinerate, Coldsnap, or Rupture Debuff triggered on the Defender is immediately Purified and applied to the Attacker. Each time this effect triggers, the Defender will Regenerate 5% of their Max Health. Knocking Down the Defender refreshes the cooldown and increases future cooldown timers by 1 second(s).
