It is one of three possible powers gained from the quest "Black Book: Untold Legends".
"Summons a spectral drum that plays for 300 seconds, improving Stamina Regen for you and nearby allies."
When activated, a floating spectral drum is summoned that emits musical notes. It grants the following bonus as long as it's active:
- Fortify Stamina Rate: 50% for 300 seconds in a 250 ft radius.
- This power is useful for vampire characters, due to their lack of stamina regeneration when in sunlight.
- It's also helpful for countering the Damage Stamina Regeneration effect from Necromancer Amulet, albeit only increased it by 25%.
