Amulet of Despair

Any time you are Charmed, you may choose to activate the amulet, and suffer in Despair instead. The creature who charmed you must pass a saving throw equal to the saving throw they imposed on you, or also suffer Despair. Despair lasts for 1 minute, or until a creature you can hear makes a successful DC 15 persuasion check to snap you out of your negative mindset.

Despair. You become immune to being Charmed, as you are too engrossed by your own negative thoughts to percieve another's commands. As your will to live fades, all of your saving throws are done at disadvantage.
