Bewildering Substitution

You sow dissent among your opponents by making one of them believe an ally and an enemy have switched places. Choose a creature you can see within range. That creature must make a Wisdom saving throw. On a failure, the closest ally of that creature has the appearance, voice, clothing, and gear of its nearest enemy, and that enemy looks and sounds exactly like the target’s nearest ally. Both the ally and the enemy must be within range, and the effect ends immediately if either moves out of range. The illusion only affects the target.
