Army of the Dead

This spell rips open the veil between the living and the dead, causing an undead army to rush through and serve the caster until they are pulled back to their realm shortly thereafter. Your spell opens a hole in the veil within range, causing an army of 2d6 skeletons, 2d8 skeletons riding warhorse skeletons, 1 bone knight, and 1 giant skeleton to rush through into the land of the living as the veil closes behind them, and lasting until the spell ends or they are killed, when they all fade away, back to the land of the dead, leaving behind no corpses, even if they did technically die.

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 60 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.
