Blood Boil

A intense shockwave of heat erupt from you causing the blood within the veins of creatures around you to to flash boil for a moment.

Every creature within 30 feet of you must make a constitution saving throw. On a failed save the creature takes 4d6 fire damage and temporarily black-out, causing them to be stunned until the end of their next turn. On a successful save the creature takes half damage and is not stunned.

This spell has no effect on Constructs and other creatures without blood.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
