Death's Shadow

Choose up to 3 corpses of medium or small humanoids within range. Each corpse becomes a ghoul under your control. (The DM 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 400 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 12 hours, after which it returns to a corpse. To maintain control of the creature for another 12 hours, you must cast this spell on the creature before the current 12-hour period ends. If you use this spell, you reassert your control over up to three creatures you have animated with this spell, rather than animating new ones.

If the creature is more than 4000 feet away from you, they return to corpse.

At Higher Levels. The number of ghouls increases by 2 for each spell slot level above 3.

At Higher Levels. Instead of creating ghouls, at sorcerer level 5 you can expend three ghouls to create a ghast or wight. At sorcerer level 11, you only need to expend two ghouls for ghasts and wights. at level 17, you ghasts and wights have 5 temporary hit points when you summon them or cast this spell again.
