Crystal Javelin

You conjure a short spear of transparent crystal and hurl it with magical force at a single creature. Make a ranged spell attack. On a hit, the target takes 1d6 magical piercing damage and a Large or smaller creature is pushed back 5 ft. 

This damage increases by 1d6 at 5th level (2d6), 11th level (3d6), and 17th level (4d6). Additionally, the distance the target is pushed is increased by 5ft. at 5th level (10 ft.) and 11th level (15 ft.).

"This sorcery is crude and brutish, but effective. One of my students accidently created it amidst an argument with one of his companions. Though the recipient survived the incident, their friendship did not." - The First Paledrake.
