Adaine's Furious Fist

For the duration of this spell, your fist gleams with silvery arcane light. You may as an action make a melee spell attack against a person within reach. The first successful hit with this attack deals 2d10 force damage to the target, and the target must make a strength saving throw or be knocked prone and be pushed 5 feet away from you. By using spell slots of higher level, the damage increases by 2d10 and the distance pushed back increases by 5 feet for every level above 1st
