Traits

  • Avatar 
    Having an Avatar on your bench or board transforms all other Avatars in your shop to the Trait of that Avatar.

An Avatar's chosen Trait is counted twice for Trait bonuses.
  • Coven 
    Gather Essence by killing champions, plus more by losing player combat. 

Beginning at 40 Essence, choose to convert Essence to rewards or continue gathering Essence. Each reward requires increasing amounts of Essence.

Lux (Coven) enables

  • Mana

    The unit-level resource that gates ability casts — champions cast once their mana bar fills, so low-mana units cast more often than high-mana ones. Spear of Shojin (mana per attack) and Adaptive Helm (amplifies Mana from all sources) push casts faster, alongside starting-mana augments.

Lux (Coven) benefits from

  • On Cast

    This effect triggers the instant a unit casts its ability. Items like Lich Bane and the Invoker Emblem reward you for landing as many casts as possible.
