Abyssal Carcass

Armor (plate), legendary (requires attunement)

This blood-red +2 plate looks like an amalgam of bodies assembled together in gruesome fashion.

The helm features imbricate howling faces; the torso seems to have been eviscerated to expose mutilated entrails, while arms and legs are woven of braided muscle fibers interwoven in agonizing fashion. Dark veins and blood spatters tint the whole surface of the abyssal carcass.

Despite a dreadful appearance, the abyssal carcass actually guards you from the true horrors of the Abyss, while serving as a reminder of the atrocities perpetrated by its inhabitants. You have advantage on saving throws against spells and other magical effects used by demons, and damage resistance against attacks made by demons. Whenever you take damage from a demon, for one hour you gain darkvision 60 ft., and are treated as chaotic evil for all effects.
