Agua Regia

Substance, common

This acid is exceptionally strong, capable of dissolving gold and other metals.

Attack. As an action, you can splash the contents of this vial onto a creature within 5 feet of you or throw the vial up to 20 feet, shattering it on impact. In either case, make a ranged attack against a creature or object, treating the acid as an improvised weapon. On a hit, the target takes 2d6 acid damage.

Use an Object. When applied to non-magical metals, up to one cubic foot of metal can be dissolved with a quiet hissing noise over the course of one minute. When applied to hardened Alchemical Glue, the glue dissolves instantly.

If the user has proficiency in Alchemist Supplies, the acid’s damage increases by their proficiency bonus.
