Mystic Reverb is a Tier 4 Spirit Item that provides Spirit Lifesteal.

It has a passive that grants an imbued ability:

  • Bonus lifesteal for any bullet and/or spirit damage dealt,
  • Allows it to slow the target and nearby enemies on initial hit,
  • and after a brief delay, Deals half of the imbued ability's damage to the target and enemies near the target.

It can be purchased from the Shop for Souls6,400.

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

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
