Bombuku’s Basalt Bottle

Wondrous item, common

Component: pouch of Dragon (black) scales

When an attack or effect would deal acid damage to a target within 5 feet of you while you hold this bottle, you can use your reaction to try and capture some of the acid. Make a Dexterity (Arcana) check with a DC equal to one-quarter of the acid damage dealt (minimum of 10). On a success, you reduce the damage by 2d10, and the bottle gains an equivalent number of charges as it fills with the caustic substance. You can’t use this reaction again until the bottle loses its charges.

Unleash. As an action, you can unstopper the bottle and point it in a direction. Acid splashes out in a 15-foot-cone, and each creature in the area must make a DC 11 Dexterity saving throw. On a failure, the target takes acid damage equal to the number of charges in the bottle, and all the bottle’s charges are lost. After this property is used, the bottle is destroyed. If you unstopper the bottle other than to use the Unleash property, all charges are lost and the bottle is destroyed.

---------------------------------

Uncommon variant: Increase the DC to 13. A creature that succeeds on the saving throw against the Unleash property takes half as much acid damage. The bottle isn’t destroyed if the Unleash property is used or if it’s otherwise unstoppered.
