Quiver of Boosting

Anytime the player successfully uses any kind of HP damage inflicting ammunition token (not just arrows) to augment a missile attack, that attack deals +2 Damage.

The damage bonus from this item is triggered by every legitimate* use of an ammo token. If the equipper of this quiver has the ability to use more than one ammo token per attack (e.g., Figurine of Power: Brownie), as long as the attack successfully hits and deals damage, each ammo token turned in* deals +2 damage.

Even if you are able to equip more than one quiver, ammunition cannot simultaneously benefit from more than one quiver at a time.

*You can’t turn in a hoard of ammo tokens to the DM to “infinitely” pump up your damage–all ammo tokens need to be used correctly.
