Artanzar's Craft Undead

This spell creates a weak undead servant, ideal for the start to other incantations of undeath. Choose a pile of bones or a corpse of a Medium or Small humanoid within range. Your spell imbues the target with a weak imitation of life, raising it as an undead creature. The target becomes a zombie. You have the zombie's game statistics, and the zombie's current hit point count is set to 1.

On each of your turns, you can use a bonus action to mentally command any zombie you made with this spell if the creature is within 60 feet of you (if you control multiple zombies, you can command any or all of them at the same time, issuing the same command to each one). You decide what action the zombie 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 zombie only wanders around aimlessly. Once given an order, the zombie continues to follow it until its task is complete.

The zombie is under your control for 12 hours, after which point it collapses and dies.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you animate three additional zombies created by this spell for each slot level above 2nd. Each of the creatures must come from a different corpse or pile of bones.
