Starting at 1st level your existence in a twilight state between life and death makes you difficult to defeat. When damage reduces you to 0 hit points you can make a Charisma saving throw (DC 5 + the damage taken). On a success you instead drop to 1 hit point. You can’t use this feature if you are reduced to 0 hit points by radiant damage or by a critical hit.
After the saving throw succeeds you can’t use this feature again until you finish a long rest.
You gain a +1 bonus to AC and saving throws while you wear this cloak.
While this pearl is on your person, you can use an action to speak its command word and regain one expended spell slot. If the expended slot was of 4th level or higher, the new slot is 3rd level. Once you use the pearl, it can't be used again until the next dawn.
