Baelfire

You target a single creature within 60ft and roll for ranged spell attack. On hit, the target creature takes 5d8 fire damage. The target immediately makes a CON save against the caster's spell save DC. On a failure, the target takes an additional 4d4 poison damage and is poisoned, or half damage and is not poisoned on a successful save. While poisoned, the target takes 1d4 poison damage on each consecutive turn. The target rerolls a CON save at the end of each of its turns.

Reaching out to a creature, you grasp the sins of it's soul and turn them against them, igniting the target in black and green flames.
