Alchemical Fire

As an action, you can reach into your Alchemist's Satchel, pull out a vial of volatile liquid, and hurl the vial at a creature, object, or surface within 30 feet of you. On impact the vial detonates in a 5-foot radius. Any creature in that area must succeed on a Dexterity saving throw or take 1d6 fire damage.

This formula's damage increases by 1d6 when you reach certain levels in this class: 4th level (2d6), 7th level (3d6) 10th level (4d6)
