Animate Army

This spell creates an army of undead servants. Choose any number of piles of bones or corpses of Medium or Small humanoids within range. Your spell imbues the targets with a foul mimicry of life, raising it as an undead creature. The target becomes a skeleton if it was bones or a zombie if it was a corpse (the GM has the creature's game statistics).

On each of your turns, you can use a bonus action to mentally command any creature you made 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 creatures will take and where they will move during there next turns, or you can issue a general command, such as to guard a particular chamber or corridor. If you issue no commands, the creatures only defend themselves against hostile creatures. Once given an order, the creatures continues to follow it until its task is complete.

The creatures are under your control for 2 hours, after which they stop obeying any command you've given them. To maintain control of the creatures for another 2 hours, you must cast this spell on the creatures again before the current 2-hour period ends. This use of the spell reasserts your control over up to 100 creatures you have animated with this spell, rather than animating a new one.
