King Groot is a Cosmic Champion. Being a Cosmic Champion, he has a Class Bonus against Tech Champions, but is weak to Mystic Champions.


Rising from under the canopy of a mysterious alien forest, Groot, the invincible master of plants and King of Planet X conquers all! This savage and ferocious monster from a parallel universe never met Rocket or joined the Guardians, instead he became a galactic warlord and experimented on captured humans. But now, the ruthless King's mission has been interrupted by the Collector, and he has set his sights on a new goal: hoarding all of the abundant treasure and power The Contest has to offer!

Strengths and Weaknesses


  • Opponents that rely on Defensive Buffs such as Regeneration and Armor Up (e.g. Ultron, Iron Man) will be hard countered by King Groot's Poison and Armor Break.
  • King Groot's high physical damage makes him great for beating down champions with low physical resistances.


Recommended Masteries

  • Extended/Enhanced Fury: With how essential King Groot's Fury Buffs are, it's a good idea to increase their effectiveness and duration.
  • Despair: With the ability to apply a permanent Armor Break you can also apply a permanent regen debuff.
  • Double Edge: Increased Attack for a passive that you're immune to? Sign me up!
  • Recovery: With Unyielding Might + Savagery Unleashed, you will be healing a lot during fights. Get this for some boosts to that healing.
