Toxic Ooze

You extend your hand and release a glob of toxic ooze. Make a ranged spell attack. On hit the target takes 1d8 acid damage. The target must then make a constitution saving throw, on a failure the target take 1d4 poison damage at the start of it’s next turn. 

The spell damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
