Poison

Legendary (Ingested)

Applied to food or beverage. A creature that consumes this poison must make a Constitution saving throw with a DC equal to the crafter's Poison DC. On failure, the next time the creature falls asleep they enter endless slumber in stasis. They do not wake and can’t be roused by any normal means. A creature sleeping in this way doesn’t require food or drink, and doesn’t age.
This effect can only be ended by greater restoration cast at 7th level or higher, or wish.
