Ethereal's Furious Fists

For the duration of this spell your fist gleams with silvery, arcane light. As an action you may make a melee spell attack against a creature you can see within range of your unarmed attack. On a successful attack during the duration of this spell deals 2d10 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 2d10 and the distance the target is pushed on a failed save increases by 5ft for each slot level above 1st.
