Pontori

Pontori is the earliest known attempt by spellcasters meant to specifically eliminate the undead.

Spell Description
During the third Age of Darkness, Sosaria, this enchantment was available to all practitioners of divine magic at the time. When used against an aggressive party of skeletons, zombies, or ghouls, it had a 50% chance of destroying a random portion of the opposing force (from one to 8 attackers). The spell's only fallacy was that it could only be attempted once in any given combat, whether the creatures were successfully destroyed or not, and regardless of which spellcaster attempted it. Despite this drawback, Pontori was an indispensable part of any divine arsenal, as it caused no expenditure of the caster's mana.

After the fall of Exodus, the effects of this spell were reduced somewhat in the Repel Undead spell.

Trivia

 * Due to Ultima III's random method of choosing which opposing creatures are destroyed, Pontori can occasionally be cast successfully, but not affect any targets.
