This is a gigantic, oak, chair with a red, velvet, cushioned seat and finely carved designs lining the arm rests and back rest. Long ago this chair was a throne for the Demon Lord Fraz-Urb'luu, the Prince of Deception. His very presence on this chair was enough to curse it with a maddening curse. When an intelligent creature sits upon this chair, they must make a DC 23 Wisdom Saving Throw. If the target fails, roll a D100 to determine the madness that takes your mind.

1-20: Your mind is taken over by the Demon Lord and the DM decides what happens.

21-40: You hallucinate images of horrible monstrosities and terrible demons.

41-60: You zone out of reality and begin to magically daydream.

61-80: The closest creature to you is planning to betray and kill you very soon.

81-100: You suffer violent delusions where your friends become foes.

If action is taken to directly oppose the will of the Demon Lord, the target suffers 8d10 psychic damage and is stunned for 1 round.

If you succeed, you may attune to the chair. While attuned and sitting in the chair, you have advantage on all Persuasion, Deception, Intimidation, and Insight checks. You also cast the spell Detect Thoughts and any creature targeted by this spell has disadvantage on their Wisdom Saving Throw. If you do not sit in the chair for 1 tenday after attuning, you lose your connection and in doing so, take 5d10 psychic damage. 

Notes: Charmed, Stunned, Target can be cured by using Greater Restoration or another similar means of magic removal.
