Blood Boil is a spell that epitomizes the cruel and visceral nature of necromantic magic, a sinister invocation that causes the very lifeblood of a target to seethe and churn within their veins. This spell is more than a mere infliction of pain; it's a deep, disturbing manipulation of the body's most vital fluid, turning it into a weapon against the self.


When the caster utters the incantation, their voice seems to carry the echoes of a thousand tormented souls. The air around the target thickens with a palpable sense of dread, and the victim's veins visibly darken as their blood begins to simmer and roil.


The effects of Blood Boil are as agonizing as they are terrifying. The target's blood heats to an unbearable temperature, causing excruciating pain that radiates from their core to the tips of their limbs. The heated blood rushes through their body, scalding them from the inside.


On a failed save: The victim suffers not only the immediate pain of their boiling blood but also the longer-lasting effects of such a traumatic experience. They take 6d8 necrotic damage as their body struggles to cope with the unnatural heat. The intense agony inflicts one level of exhaustion, a testament to the spell's ruthless efficiency. The physical and mental toll of experiencing one's blood turn against them is a horror few can comprehend.


On a successful save: The target's blood heats up but doesn't reach the critical boiling point. They take half as much damage and avoid the debilitating exhaustion. However, the sensation of their blood heating up, even momentarily, is enough to instill a deep-rooted fear of the caster's dark capabilities.


Creatures immune to necrotic damage or lacking blood, such as undead or constructs, find themselves impervious to Blood Boil. This immunity underscores the spell's reliance on the living, pulsing essence of blood - a medium through which life and death intertwine.


Blood Boil is more than a spell; it's a gruesome testament to the necromancer's control over life and death. It's a favorite among those who seek to inspire terror through the most primal and intimate form of suffering - turning the very essence of life into an instrument of torment.
