Boneyard

7-level Necromancy

Casting Time: 24 hours

Range/Area: Touch

Components: V, S, M (enchanted bones, incense, and herbs worth at least 1000 gold, which the spell consumes)

Duration: Until Dispelled

You touch a point and infuse an area around it with osteomancy. The area can have a radius of up to 120 feet, and the spell fails if the radius includes an area already under the effect of a boneyard or hallow spell. The affected area is subject to the following effects.
First, you know the exact location and hear the thoughts (if any) of any undead creature within the area, and you know if they are under someone’s control.
Second, all creatures within the area lose resistance and immunity to necrotic and piercing damage.
Finally, as a reaction whenever a non-undead creature dies within the area, you can choose to rip its skeleton from its flesh and force it to rise again under your control. If you do, the creature is resurrected with 1 hit point, its creature type becomes undead, it becomes immune to all damage, it loses access to any legendary actions it had (if any), and you can mentally command its actions. At the end of its next turn, it dies and cannot be resurrected by any means short of a wish spell.
