Viper's Spit

You spit a venomous bile at a target up to 20 feet away, making a ranged spell attack roll as you do so. The target must succeed on a CON saving throw or take 1d4 poison damage and suffer the poisoned condition until the end of their next turn. This spell’s damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
