Azuth's Mighty Push

You jam a staff or rod into the ground, everyone in a 10 ft. radius of the caster must make a strength saving throw. On a failed save the target takes 2d8 force damage and is pushed 15 ft away from you and is incapacitated. On a succes the target only takes half damage and isn't pushed away.

The damage and area of effect increase to 15 ft. and 3d8 damage if using a 5th level spell slot, 20 ft. and 4d8 damage if using a 7th level spell slot
