You force your open palm towards a chosen creature and create a wave of forceful energy to knock it away from you.

The targeted creature must succeed on a DC 15 Constitution saving throw or be forced 1d10, plus your spell modifier, feet away from you. If the targeted creature failed the check by 10 or more the creature is knocked prone. 

Additionally, if the targeted creature collides with any solid obstacles when forced back, they will take 1d4 bludgeoning damage from the collision. Add 1d4 to the damage taken for every 10 feet of distance the creature was forced back before colliding with the obstacle.
