Endless Slumber

You cause a creature within range to fall into an endless slumber. The target must have the Unconscious condition to be affected by this spell, and must make a Charisma saving throw. On a failure, the creature has the Unconscious condition extended for the duration. Constructs and Undead are immune to this spell.

While Unconscious in this way, the target no longer needs to eat or drink, ceases to age, and has Resistance to all damage. The Dispel Magic spell has no effect on the target, but a Remove Curse spell cast using a spell slot of Level 7 or higher ends this effect.

Using a Higher-Level Spell Slot. When you cast this spell using a spell slot of Level 8 or higher, the required level of spell slot needed for Remove Curse to end this effect increases by 1 per level of spell slot above 7.
