Boiling Blood

Choose a target within range. That target’s skin begins to redden as its blood starts to boil within its veins. It takes 2d6 fire damage, and another 2d6 fire damage at the start of each of its turns. An affected creature can make a Constitution saving throw at the end of its turn. On a success, the spell ends.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
