Tempest Shield

A more powerful version of the Tempest Strike, the Tempest Shield spell hurls a wave of swirling storm-winds crackling with electrical energy toward a creature within range. Upon a successful hit the target takes 1d10 Force damage and is pushed backwards 10 feet in a straight line.

The spell creates more than one wave when you reach higher levels: two waves at 4th level, three at 10th level, and four waves at 16th level. You can direct all of the waves at the same target or at different ones. Make a separate attack roll for each wave.
