Tyrant’s Whip

Weapon (whip), uncommon

This wicked whip has 3 charges and regains all expended charges daily at dawn. When you hit with an attack using this magic whip, you can use a bonus action to expend 1 of its charges to cast the command spell (save DC 13) from it on the creature you hit. If the attack is a critical hit, the target has disadvantage on the saving throw.
