Mystic Reverb is a Tier 4 Spirit Item that can be purchased from the Shop for  6,400.

Notes

• The debuff effect is applied to the first enemy hit. If the imbued ability is an area-of-effect and it hits multiple heroes, only one enemy will receive the debuff.

Notable Interactions

• Pure Damage does not trigger the reverb or use the imbued lifesteal. If an ability has bonus Pure Damage like the blessed stakes of Venator's Ira Domini, it will not be used to calculate the damage of the reverb.
  • Mystic Reverb can be imbued on Lady Geist's Soul Exchange, but it has no effect.
• Abilities that only deal Melee Damage such as Viscous' Puddle Punch or Calico's Leaping Slash can be imbued, though they cannot activate the reverb or use the imbued lifesteal.
  • Spirit Snatch applies after the melee damage and does not allow melee abilities to use Mystic Reverb.
  • However, Quicksilver Reload and Mercurial Magnum grant bonus spirit damage to the imbued ability's first hit of weapon or spirit damage and can activate the debuff.
• The debuff can store damage from items like Quicksilver Reload or Tankbuster on the imbued ability.
• The 50% extra damage is calculated based on pre-mitigation damage, but can then still be mitigated by spirit resistance when it triggers.

Known Bugs

• The initial reverb damage can kill the primary target, but is sometimes non-lethal to secondary targets, leaving them with at least 1 hp remaining. This seems to mainly happen against Target Dummies in Sandbox
