Dire Charm

You enchant one humanoid within range with a primordial faerie enchantment. The target must make a Wisdom saving throw or be charmed by you, regarding you as a friendly acquaintance until the spell ends. The target automatically succeeds on its saving throw if you or your allies are fighting it. If you or your allies deal damage to it or force it to make a saving throw to resist a harmful effect, the spell ends early. After the spell ends, the creature knows it was charmed by you.
