Svefnthorn Rite

You trace the Svefnthorn, an ancient bindrune of slumber, as you chant words once whispered by rune-singers. Undead within range feel the weight of true rest tug at their souls.

Each undead creature of CR 2 or lower within range must succeed on a Charisma saving throw or fall prone and become Incapacitated for the duration. Affected creatures that have 25 hit points or fewer instead fall Unconscious until the spell ends, the creature takes damage, or someone uses an action to shake them awake.

Undead of CR 3 or higher must make the same saving throw with advantage. On a success, they resist the rite entirely.

Often invoked at burial sites where the dead have not stayed still.
Traditionally etched into stone staves or funeral horns, with the Svefnthorn carved in iron.

By thorn of sleep and rune of stillness, return to the peace you defy.
