The Crooked Moon Campaign Setting
0-level (Cantrip) Transmutation
You touch a creature or nonmagical object and break the target’s substance down into its most fundamental components. Make a melee spell attack. On a hit, the target takes 1d8 Force damage, and its AC is reduced by 1 against the next attack roll made against it before the end of your next turn.
The damage increases by 1d8 when you reach levels 5 (2d8), 11 (3d8), and 17 (4d8).
