This spell creates a song that creatures find harsh and jarring because of its lack of harmony. Their ability to reason becomes diminished, and is replaced by a blinding hatred of those nearby. Each affected creature has a chance to attack the nearest target each round, be it friend or foe. When you are done casting the spell, make an Expression check. Your result + 35 is the percentage chance that each creature will attack its nearest neighbor each turn. A creature that does not attack its nearest neighbor is free to act normally for that round. The chance for creatures to attack their neighbors increases 5 percent each additional round.
Creatures forced by a song of discord to attack their fellows employ all methods at their disposal, choosing their deadliest spells and most advantageous combat tactics. They do not, however, harm targets that have fallen unconscious.
