Yenma's Palm of Pushing

You expel kinetic force in a 30ft line in front of you. Any creature in that line that are a size of Large or smaller must make either a Strength of Dexterity (Defender's Choice) saving throw versus your spell save. On a failed save the affected creature is pushed 10ft. and is knock prone. Additionally this spell can be used to knock done or break through a wooden surface such as a wooden door.
