Book of Vile Darkness 3.5
By Monte Cook
Once per day, the wearer of this +1 breastplate can transfer the damage dealt to him from a melee attack to another creature, other than the attacker, within 100 feet. If the other creature succeeds at a Fortitude save (DC 16), the creature takes no damage and the wearer of the grim defender armor takes double damage.
