Animate the Dead

This spell creates an undead servant. 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 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 under your control for 72 hours, after which it stops obeying any command you've given it. To maintain control of the creature for another 72 hours, you must cast this spell on the creature again before the current 72-hour period ends. This use of the spell reasserts your control over up to four creatures you have animated with this spell, rather than animating a new one.

You can animate a group of 4 at once but will shorten the time to 24 hours each. 

If you fail to maintain control of the undead will turn to dust and can not be reanimated.

You can cast on 2 and have 48 hours of control of both at the same time.

At Higher Levels. When you cast this spell at a level 5 you get 1 additional undead creature to used as a pack mule to hold 50 lbs of weight (Must have a backpack or extra pouches to equipped to use this ability. Each of the creatures must be a different corpse or spell will fail.
