Zombie Beacon

Wondrous item, legendary (requires attunement)

This strange monolith is small enough to be moved by cart and horse. Those who come across it feel a strange draw to own the monolith.

If someone claims the monolith, they can attune to it by keeping it near them for 3 days. On the sunset of the third day, all dead creatures within 100 miles rise as zombies and begin to move towards the monolith.

Curse. If attuned for more than 1 day, you must make a DC 20 Constitution saving throw at the end of that day, and each month thereafter.

On a failure, you become a zombie marshall, and the beacon is destroyed. The beacon cannot be unattuned or separated from you unless you are subject to a remove curse. The beacon can be destroyed otherwise by impaling a zombie marshall against it and reciting a holy scripture.
