Collar of Undead

Some people have no qualms about exploiting any opportunity for profit, including the sorrow caused by the loss of a loved one. Such people will undoubtedly make good use of the Collar of Undead, whether as professional smugglers looking for wealthy widows or widowers to plunder, or dark sorcerers in need of souls. This magical collar, when placed around the neck of a recently deceased person, will animate the body again, making it capable of many simple actions on command. The risen corpse will also be able to repeat words specified by the person who placed the collar on them. It is no surprise, then, that some desperate people will let themselves be abused by the hope of using this object to keep their loved one with them a little longer. When placed around the neck of a humanoid creature that has died within the last 10 days, and is Large or smaller, the creature comes back to life with 1 hit point. The creature becomes undead and is subject to all features that affect undead. The creature does not need to eat, sleep, or breathe. At dawn each day, the creature's hit point maximum decreases by 1d4 as its body rots and decays. When the creature's hit points reach o, it falls apart into a heap of dust and is destroyed. While wearing the collar, the creature is under your command and follows your orders to the best of its ability. On your turn you can issue a command to the creature as a Bonus Action. If no order is given, the creature follows any previous commands given and defends itself to the best of its ability. If the collar is removed from the creature that it has brought back to life, the creature is immediately reduced to 0 hit points.
