This black leather armour +1 is often crafted by witches to be worn by the Witch Knights sworn to protect them. Anyone touching, through grappling or otherwise, the Death Armour receives 2d6 points of Acid damage.
Death Armour’s acid effect is dormant when not being worn, so it can be put on without burning yourself.
