Tankbuster is a Tier 3 Spirit Item that can be purchased from the Shop for Souls 3,200. Its component, Mystic Burst, makes up Souls 800 of the cost.

Notes

  • Tankbuster is a Charge-Up item, thus not affected by Cooldown Reduction.
  • Tankbuster only goes on cooldown when it affects enemy heroes. It will not go on cooldown when you hit an NPC.
  • While the tooltip only specifies "Abilities", only Spirit Damage will activate Mystic Burst. Abilities dealing Weapon, Melee or Pure Damage will not activate Mystic Burst (unless they have a Spirit component).
  • Tankbuster has inconsistent interactions with different sources of damage resist and amplification.
    • Spirit Resist Reduction on target helps trigger Tankbuster. For example, an ability that would otherwise deal 160 damage, when striking a target affected with   Mystic Vulnerability will trigger Tankbuster.
    • Spirit Resist on target does not prevent Tankbuster from triggering. For example, an ability that deals 170 damage, when striking a target with   Spirit Resilience will still trigger Tankbuster.
    • Most other sources seem to not affect the trigger, but more testing is required to confirm that.
  • The triggering of the additional damage is entirely unaffected by the target's barriers (or lack thereof).
  • The additional damage, and the ability which triggered the additional damage, are applied to the target as separate instances of damage. The additional damage from Tankbuster is dealt after the original spell damage.
