Sounds

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

It has a passive that allows an imbued ability to Slow the target and nearby enemies on hit, then 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  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

• Mystic Reverb can be imbued on Lady Geist's Soul Exchange, but it has no effect.
• 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 Sanbox
