Grievous Venom

Dealing damage to an enemy champion reduces any shields they gain by 50/75%, and applies 40% Grievous Wounds for 3/4 seconds. If an enemy heals for more than 60% of their maximum health while continously affected by Grievous Wounds, it is increased to 80% Grievous Wounds. Grievous Wounds reduces the effectiveness of Healing and Regeneration effects. Only reduces General and Physical Damage shields, but not purely Magical Damage blocking shields.
