Animate Friend

This spell creates an undead servant. Choose a pile of bones or a corpse of a Medium or Small humanoid within range. Your spell imbues the target with a foul mimicry of life, raising it as an undead creature. The target becomes an undead creature of your choice with a challenge rating below 1. It could be a skeleton if you chose bones or a zombie if you chose 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 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.

The creature is under your control for all of eternity, or until it's hit points reach zero.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the challenge rating of the undead creature you can summon increases by one.
