Knockback Jinx

Taught in first year Defence Against the Dark Arts. You choose a target within 30ft and the target must succeed a dexterity saving throw or be knocked backwards 10ft and take 1d10 bludgeoning damage (on a failed save, it takes half damage). It can also be used to push heavy objects, up to 500lbs.

Using the incantation Flipendo Duo, the maximum weight increases to 750lbs, the knockback increases to 20ft and damage increases to 2d10, and using Flipendo Tria, the maximum weight increases to 1000lbs, the knockback increases to 30ft and damage increases to 3d10.
