Create Greater Undead.

Choose up to three corpses of Medium or Small humanoids within range. Each corpse becomes a Skeleton Guarder, Skeleton Mage or a Skeleton Legionnaire under your control. (The GM has game statistics for these creatures.)

As a bonus action on each of your turns, you can mentally command any creature you animated with this spell if the creature is within 120 feet of you (if you control multiple creatures, you can command any or all of them at the same time, issuing the same command to each one). You decide what action the creature will take and where it will move during its next turn, or you can issue a general command, such as to guard a particular chamber or corridor. If you issue no commands, the creature only defends itself against hostile creatures. Once given an order, the creature continues to follow it until its task is complete.

The creature is permanently under your command, following your verbal orders to the best of its ability. The undead created by this spell will remain loyal to the creator and cannot be charmed or controlled by anyone other than the creator.
