Animus' Raise Revenant

You can cast this spell only at night. Choose a corpse or other sensible remains (determined by the GM) of a non-undead creature within range. This creature is then raised as an undead under your command. The creature has the statistics of an undead of CR 2 or lower (they are your choice, however they must correlate to the corpse used. For example, you cannot get an ogre zombie from a dead rat). (The GM has game statistics for these creatures.).

As a bonus action on each of your turns, you can mentally command the creature you animated with this spell if the creature is within 120 feet of you. 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 until you cast this spell again, at which point it will perish and the soul or holy relic used to animate it returns to its rightful deity.

At Higher Levels. When you cast this spell using a 6th-level spell slot or higher, the creature you animate may be of one additional CR higher for every level above 5th it is cast at.
