Notes

• Mystic Burst uses Charge-Up
• Heroes with Spirit Lifesteal will heal from Mystic Burst's passive effect triggering.
• A small lightning shock visual is applied to the enemy hero when it is hit by Mystic Burst's passive effect.
• When the target is hit with spirit damage, the damage value which is compared against the triggering threshold is the base damage value prior to any increases or decreases from damage amp, damage reduction, spirit resistance, and spirit resistance reduction.
  • Damage amp and spirit resist reduction will not help you in achieving the damage threshold to trigger the passive.
  • Damage reduction and the target's spirit resistance will not prevent the passive from triggering when it otherwise would.
• 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 Mystic Burst is dealt after the original spell damage. This has implications for abilities or effects that rely on single instances of damage, for example:
  • Vindicta uses assassinate on an enemy Warden. The baseline Assassinate on its own is not enough damage to kill the Warden, but the increased damage (due to the additional damage from triggering Mystic Burst) is enough to secure the kill. Since the additional damage from triggering Mystic Burst is applied after the Assassinate, it is technically the item's damage which secures the kill, not the Assassinate. Thus, Vindicta will not receive bonus weapon damage from Assassinate's passive.
