Sibling Rivalry (3.5e Spell)

When struck by this spell and at the beginning of each of their turns after the first, the target of this spell must make a Will save. If they fail, they become consumed with jealousy towards their allies, abandoning any previous allegiances even to their closest friends or direct relations. While under this spell’s effect, the target must attack the closest allied creature to them and can take no actions that do not involve attacking, preparing, or moving to attack. While not under the direct control of the caster, the affected creature should use the most deadly means available to them in attacking.
