5th level Necromancy
Classes: Magus, Sorcerer, Witch, Wizard
Domains: Fire
Components: V, S, M (a drop of mercury)
Casting Time: Standard
Range: Touch
Target: One living creature
Duration: 3 rounds
Saving Throw: CON negates
Spell Resistance: Yes
Description: The temperature of the target creature's blood (or other similar body fluid) begins to rise over the next 3 rounds during the caster's turn. Each round starting with the first, the target creature attempts a new saving throw at the start of the caster's turn to resist that round's effect. A successful save does not end the spell effect, but does prevent that round's effect. On each round where the target fails to resist the spell, he gains one level of fatigue. On the second failed round, his capillaries burst, dealing 1d6 points of Constitution damage. On the third failed round (if any), the target's blood begins to boil dealing 10d6 fire damage.
Leveling: For each level above 5th, the final round does an extra 2d6 fire damage.
