Coffin of Undeath

If you place a humanoid corpse inside this coffin and close the lid for 24 hours, it will emerge as an undead creature. That undead is considered to be charmed by you. You do not control it, but it considers you to be a trusted ally who will listen to and follow your suggestions. Once you use this ability, you cannot use it again for 2 days.
If the undead normally has an Intelligence of less than 10, its Intelligence rises to 10.
The creature created is determined by the power of the humanoid placed within, at the DM's discretion.
