Dragon's Claw

Fire envelops your hand to deliver a flaming strike to a creature you try to hit. Make a melee spell attack against the target. On a hit, the target takes 1d12 fire damage, and its movement is reduced by 10ft at the start of its next turn.

The spell’s damage increases by 1d12 when you reach 5th level (2d12), 11th level (3d12), and 17th level (4d12).
