Triple Airstrike

You create a small air bubble right before you punch your traget, wich "explodes" on impact.

You do this 3 consecutive times.

Make 3 melee spell attack rolls, each dealing 1d8 force damage.

The target is pushed back 5ft for every hit, up to a total of 15ft.

At Higher levels, the damage increases by 1d8 and the distance that the target is pushed back by 5ft.

At level 7 (2d8, 10ft per hit)

At level 14 (3d8, 15ft per hit)
