This magic item originally appeared 17 Relics by The Le Press. A relic is a powerful magic item which once formed part of the body or belongings of some great figure. See Seventeen Relics for special rules on relics.
Long ago, two young elven scribes were taken captive by a ruthless lich. The boys were kept locked up and fed poorly for centuries - for most of their natural lives. Both attempted suicide on several occasions, only to find their wounds healing instantaneously through some unknown curse placed in their cell. Anger at their captor filled them and bubbled like a kettle of water on a stove. Eventually, the rage became too great, and one of the elves turned on the other without reason, murdering him with his bare hands. The anger took too great a toll on the survivor who died on the spot of a heart attack, and the lich harvested one of his bones for use as a powerful relic.
The Bone of Contention holds such hatred that the mere sight of it can drive a man to violence. To use it, the wielder must hold it forth, which is a standard action that does not provoke attacks of opportunity, similar to turning undead. Anyone viewing the bone is inexplicably inspired to anger and feels a compulsion to attack the nearest person or creature, believing them to be an enemy. They must succeed at a Will save (DC 15) or else succumb to this urge, which they follow for one minute or until their target is incapacitated or dead. The current holder of the bone and his allies are immune to its effect, but feel a faint and ineffectual hatred if they stare at it.
However, the bone has a drawback. Once per month at a seemingly random time, the owner of the bone must make a successful Will save or become suddenly filled with hatred and immediately believe that the next person he sees is an enemy. This mental illusion lasts for one hour, after which the owner of the bone regains his senses.
