6-level Necromancy
You throw three minotaur teeth on to the ground in front of you. At the start of your next turn, three minotaur skeletons erupt from the ground, fully formed. You can use a bonus action to shout commands at the minotaur skeletons if they are within 100 ft. of you. Your commands must be general orders, such as "attack that enemy" or "guard this room." Once given an order, the minotaur skeletons will continue to follow it until the task is complete or until you issue another command. If the minotaur skeletons are given no commands, they will attack the nearest creature. When the spell ends, the minotaur skeletons dissolve into bone dust.
At higher levels: When you cast this spell using a spell slot of 7th level or higher, you animate an extra minotaur skeleton for each slot level above 6th.
