Prismal's Revenge

This sinister dweomer inflicts a potent, cursed disease upon the creature touched. A creature failing a saving throw vs. spell immediately falls prey to a massive onslaught of dangerous maladies. The curse causes new diseases to constantly manifest in the victim's body, overwhelming his system and killing him within four days. Even a paladin can fall prey to Prismal's revenge.

An afflicted victim must succeed in a second saving throw vs. spell, with a -4 penalty, or suffer the side-effects of Prismal's revenge: Each day that the curse progresses, ability scores, movement rate, and hit points are reduced by 25%, and THAC0 and saving throws worsen by 1d4 points. Prismal's revenge is not contagious.

To defeat the curse, a dispel magic must first be cast in order to stop the part of the spell that continuously regenerates the curse; then remove curse must be cast to halt the continuing manifestation of diseases; and finally cure disease is required to defeat the current infections. (A properly worded wish may be effective, also.) If these spells are not cast in the proper order, and within the same turn, they have no effect: If only a cure disease is cast, the curse immediately reinstates the disease, and if a remove curse only is cast, the magic of the spell reinstates the curse.

The casting of Prismal's revenge is an evil act. The late necromancer Purdue Darkwolf also claimed authorship of this spell. (The claim, it is suspected, led to his demise.)
