Grievous Wounds icon Grievous Wounds is a debuff that reduces all Heal power healing received by 40% / 60%.


Champion abilities




  • Hybrid resistances icon Shields are a way of temporarily adding health to a champion that is not reduced by Grievous Wounds.
  • A champion debuffed by Grievous Wounds has the icon on top of them.
    • The size of the icon is bigger based on the percentage application (60% has a much larger icon than the icon for 40%).
  • Grievous Wounds does not stack; the duration of the Malefic Visions debuff will overlap on separate effects and refresh on the same effect, while prioritizing the most potent application.

  • Grievous Wounds is generally used to limit or minimize the healing, Spell vamp icon spell vamp, or Life steal icon life steal of one enemy champion ability such as Darius OriginalSquare Darius' Decimate Decimate, Renekton OriginalSquare Renekton's Cull the Meek Cull the Meek or Sylas OriginalSquare Sylas' Kingslayer Kingslayer. It can also weaken burst healing champions such as Aatrox OriginalSquare Aatrox, Dr. Mundo OriginalSquare Dr. Mundo, Fiora OriginalSquare Fiora, Swain OriginalSquare Swain, Trundle OriginalSquare Trundle, Vladimir OriginalSquare VladimirWarwick OriginalSquare Warwick, or Zac OriginalSquare Zac.
    • Grievous Wounds isn't only useful against champions with in-built sustain. Some can build viable items or take runes that give them sustain, such as Death's Dance item Death's Dance, Bloodthirster item Bloodthirster, Conqueror rune Conqueror, or Legend- Bloodline rune Legend: Bloodline. Grievous Wounds is also useful against them. This is important to notice especially in situations where technically there are no champions with natural sustain on the enemy team, but they may own or have sources of bonus effects that would grant them sustain.
    • On the other hand, some champions only have sustain when out of combat. This includes Garen OriginalSquare Garen, Tahm Kench OriginalSquare Tahm Kench, and champions that build Warmog's Armor item Warmog's Armor. Grievous Wounds is not effective against those champions (as the debuff usually doesn't last long enough for it to have effect on them); the most effective way to prevent them from healing is to force them to stay in combat.
    • It is important to note that Grievous Wounds also affects healing from outside sources instead of just self-healing. This is especially important against Soraka OriginalSquare Soraka, which can use Astral Infusion Astral Infusion to out-sustain her enemies, even if her allies don't have sustain themselves.
  • Grievous Wounds is dispelled by Sion OriginalSquare Sion's Glory in Death Glory in Death and Death death. It will however persist through Revival icon resurrection effects (e.g. Zilean OriginalSquare Zilean's Chronoshift Chronoshift, Guardian Angel item Guardian Angel).
