Ability Details
Notes
  • The bonus attack speed from Demacian Standard's aura will apply to Jarvan IV and stack with its passive's.
  • Demacian Standard can be targeted by allied minion-targetable abilities (Teleport Teleport, Safeguard Safeguard)
  • Even though the Demacian Standard has a finite amount of health it is both untargetable to enemy basic attacks as well as immune to area-of-effect damage.
    • This makes it effectively invincible and indestructible.
