Aged Elven armor

While you are attuned to this armor you gain a +1
bonus to your AC. This Armor was made by the finest elven blacksmiths, and it's much lighter and grants a better freedom of movement than other armors of the same categories. The armor shows clear signs of age, with a few cracks along the line. 

Curse: as long as you are attuned to this item, you are also cursed in two ways. You are vulnerable to all
non magical damage. This curse can be eliminated by repairing the armor. The armor can also be strengthened by adding adamantine to it. If so, the wearer ignores the first 3 damage from any source except sonic, psychic, and necrotic. Furthermore, the armor gains another +1 to its armor class You also slowly turn into an Valenar High Elf. This change is permanent, as the Armor transfers the Elven ancestral will to it's bearer, to continue the old fight. 

Plate consists of shaped, interlocking metal plates to cover the entire body. A suit of plate includes gauntlets, heavy leather boots, a visored helmet, and thick layers of padding underneath the armor. Buckles and straps distribute the weight over the body.
