Bloodburn

Also known as bloodboil, this spell is employed only by the most diabolical dragons, as it inflicts an agonizing death on its unfortunate victim. Red dragons in particular enjoy casting this spell on presumptuous wizards and arrogant knights.

When cast on a living creature, this spell causes any liquids in the creature's body to become very hot in a matter of seconds. When cast against animals, bloodburn causes the target's blood to actually ignite within the creatures arteries and veins, inflicting 2d4 points of damage per round. (This makes spellcasting impossible while the spell effect continues.) Water stored within plants begins to immediately boil, dealing 1d4 points of damage per round. Slimes, jellies, and oozes immediately dissolve due to this spell and are instantly slain (provided they do not succeed at their initial saving throw). Undead creatures and creatures immune to fire or heat damage are unaffected by this spell.

If the target of this spell succeeds at a saving throw vs. spell, it is unaffected. Targets that fail their saving throws can attempt another saving throw at the beginning of round three of the spell's effect (after having taken a total of 4d4 points of damage) and every subsequent round at a -3 penalty. When such a target succeeds at one of these subsequent saving throws, the spell ends and no further damage is inflicted. (However, in the round the saving throw is successfully made, affected targets may still not cast spells as they are recovering their wits for the remainder of the round.)

Otherwise, the only way to halt the effect before the spell expires is to successfully cast dispel magic (or a similar incantation) upon the spell's target or to cast some form of cold spell, such as cone of cold, that totally envelops him or her. (Note that the cold spell does not inflict its normal damage.) If the cold spell is only partially enveloping (such as frost fingers spell or a cone of cold cast too closely), the bloodburn effect dies down for that round (no fire damage is inflicted), but then immediately spreads throughout the victim's fluids once again, inflicting regular damage the following round.
