Adaine's Furious Fist

For the duration of this spell, your fist gleams with silvery arcane light and you may, as an action, make a melee spell attack against a creature within reach of your unarmed attack. The first such successful attack during the duration of this spell deals 2d10 force damage to the target, and the target must make a Strength saving throw or be knocked prone and pushed up to 5 feet away from you.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the extra damage increases by 2d10 for each slot level above 1st. Additionally, the distance the target may be pushed away from you on a failed save increases by 5 feet for each slot level above 1st.
