Arcane Earmuffs

These earmuffs make your ears feel much warmer and cozy. While attuned to the earsmuffs, they vibrate with heat. While vibrating, you are deafened (which ignores immunities to the deafened condition), suppress the charmed condition, have resistance to thunder damage, gain advantage on concentration saving throws, and gain advantage on Intelligence and Charisma saving throws. You automatically succeed any saving throw that requires your to hear a sound such as a harpy's luring song.

Notes: Advantage: Charisma Saving Throws, Advantage: Intelligence Ability Checks, Immunity: Charmed, Resistance: Thunder, Advantage: Saving Throws, Deafened
