False Foes 2014

You cause a creature to be unable to tell friend from foe. The target must make an Intelligence saving throw, automatically succeeding if it is immune to the frightened condition. On a failure, it treats every other creature as its enemy and fights them with its typical tactics, and must use its reaction to make an opportunity attack against any creature that provokes one. Each time the target takes damage, it repeats the saving throw against the spell. If the saving throw succeeds, the spell ends.
