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.
  • Lunar 
    Lunar champions and adjacent allies gain Attack Speed and Ability Power. Lunar champions gain 100% more.

Lux (Lunar) enables

  • Vulnerable

    Increases the damage an affected unit takes from every source for a duration. Distinct from Sunder and Shred, which each cut one resistance stat rather than amplifying the hit, and from Weaken, which reduces what a unit deals instead of raising what it takes. It is the debuff mirror of Damage Amp — the same multiplier, applied to the victim rather than granted to the attacker.

  • 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 (Lunar) 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.
