Tolma's Furious Fist

The first time you hit with a melee spell attack during the spell's duration, you deal 3d10 force damage to the target. Additionally, the target must succeed on a strength saving throw or be pushed 5 feet away from you and knocked prone.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d10, and the distance the target is pushed on a failed save increases by 5ft, for each slot level above 1st.
