Pharaonic Headdress of Duorik Ironside

This Pharoah’s headdress is worth far more than the amber gem set in the centre of the forehead (100 gp). It is worth about 5,000 gp – and probably more to the Ironcrag Dwarfs who are descendants of the Dwarfs of Hvel-Runor.
If worn, the wearer has Disadvantage for all Dexterity (Stealth & Acrobatics) checks and Wisdom (Perception) checks, but gains Advantage for saves against psychic attacks + Resistance to psychic damage.
