Cloth of Authority is a rare piece of Clothing that grants immunity to emotion-altering conditions and grants +1 Armour Class and Advantage on Intimidation and Insight checks.
One can hardly be called a lord if they aren't dressed as such. A cursory glance at Gortash's finery would reveal intricate garb - a closer look would reveal a maddening attention to even the most minute details of the filigree.
