Alchemic Pop

Fashioning alchemical reagents into a rough explosive, you quickly slap it onto a target before detonation. Make a melee spell attack against the target, on a hit the target takes 1d4 acid damage and 1d6 force damage. Additionally, the target flinches rendering them unable to make opportunity attacks until the start of their next turn.

Cantrip Upgrade. The spell's damage increases when you reach 5th level (2d4 and 2d6), 11th level (3d4 and 3d6), and 17th level (4d4 and 4d6).
