Boiling Blood

Choose a target within range that has blood. The target must make a Constitution saving throw. On a failure, the target takes 3d8 fire damage and has disadvantage on attack rolls and ability checks for as long as the spell remains in effect. On a successful saving throw, the target takes half damage and the spell ends.

A creature under the effect of this spell take an additional 3d8 fire damage at the start of their turn and can repeat the saving throw at the end of their turn, ending the spell on a successful save.

If you cast this spell using a higher level spell slot, you increase the damage dealt by 1d8 for each spell slot above level 3.
