Burning Blood

You must possess a breath weapon to be able to cast this spell. Your very blood becomes suffused with the same element that powers your breath weapon. Whenever you take damage from an attack that breaks skin, a spurt of blood erupts in a 5-foot radius from the wound, dealing damage of said element to all creatures within range equal to your character level or CR, whichever is higher. This spell remains active for the full duration unless the caster dismisses it by using a free action, even if the caster dies.
