Baltron’s Effusive Bloodboil

Choose a humanoid creature within range. At the start of the target’s next turn, it burns with fever and sweats uncontrollably, taking 2d4 fire damage. At the start of its following turn, blood starts dripping from its eyes, ears, and nose, and it takes another 2d8 fire damage. At the start of its subsequent turn, it takes another 2d4 fire damage as the spell’s effects dissipate.

Each time the target would take damage from this spell, it makes a Constitution saving throw, taking only half damage on a success.

At higher levels. When you cast this spell using a spell slot of 3rd level or higher, the damage at the start of each of the target’s turns increases by 1d4, 1d8, and 1d4, respectively, for each slot level above 2nd.
