Dog Fart

When you cast this spell, any creature within 30ft is instantly hit with the smell of rotting flesh and must make a constitution saving throw. On a failed saving throw, they immediately take 4d6 necrotic damage and, if they remain inside the area of affect, they take an additional 2d6 necrotic damage at the start of their next turn. On a successful saving throw, they immediately take half damage and do not take additional damage on their next turn.

(This spell was created because I am a nerd who wonders what kind of damage that was after the dog farted in my face.)
