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.
  • Blackthorn 
    The ally on the Blackthorn hex is sacrificed before combat, granting your champions Health. 

Blackthorn champions gain additional stats based on the sacrifice's Role, Star Level, and Cost.

Lux (Blackthorn) 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 (Blackthorn) benefits from

  • On Cast
