Death's Door

When damage would reduce you to 0 hit points, you instead drop to 1 hit point and gain temporary hit points equal to half your hit point maximum.

As you cross the threshold between life and death, three rapid knocks echo through the area, and at the same moment your form takes on a shadowy otherworldly appearance, as though your physical body has partially crossed into the realm beyond death.

For the duration, you gain the following effects:

• Your Armor Class becomes 20 if it would otherwise be lower.
• You gain a +2 bonus to your spell save DC.
• You can't be frightened, charmed, or possessed.
• You gain a flying speed equal to your movement speed for the duration.
• You cannot be healed.

When you enter this state, each creature of your choice within 30 feet of you that can see you must make a Wisdom saving throw against your spell save DC. On a failed save, the creature is frightened of you for the duration. A frightened creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. A creature that succeeds on this saving throw is immune to this effect for the duration.

If you are reduced to 0 hit points again while Death's Door is active, you fall unconscious as normal and spell ends.

When the spell ends, any temporary hit points granted by this spell disappear.

Once you cast this spell, you can't cast it again until you finish a Long Rest.
