Blood Boil

You utter a horrifying incantation that increases the targets production of blood and turns their blood acidic. The target must make a constitution saving throw, on a fail the target takes takes 6d4 acid damage, on a success the target suffers halve the damage.

Then the pressure created by the extra acidic blood will then cause the blood to boil and burst out of the target. Each creature within a 15ft radius sphere must then make a dexterity saving throw, taking 3d8 acid damage on a fail, halve as much on a success.

In case the initial bout of d4 damage kills the target, the explosion becomes more volatile and violent, with the damage of the explosion being increased to 8d8 acid damage.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher the acid damage added to the initial bout increases by 1d4 per slot level above 3rd, and the damage of the acid explosion also increases by 1d8 per slot level above 3rd.
