An ancient diadem crafted from twisted wood from a Gigan Oak and adorned with three square-cut garnets. The garnets glow with a malevolent light.

The diadem allows an attuned wearer to create and command up to 1 CR worth of mindless undead (Intelligence of 6 or less). It is an action to raise the undead and establish control. You can use a bonus action to mentally command the creatures you make with the diadem, issuing the same command to all of them. To receive the command, a creature must be within 60 feet of you. You decide what action the creatures will take and where they will move during their next turn, or you can issue a general command, such as to guard a chamber or passageway against your foes. If you issue no commands, the creatures do nothing except defend themselves against hostile creatures. Once given an order, the creatures continue to follow it until their task is complete.

The diadem's effect lasts for 1 hour, after which the undead become inanimate once more.
