Armor of the Ages

Plate armor made in a pre-calamity style, made of a strange superalloy through long forgotten techniques.
Light and flexible, rough in texture and cold to the touch, this suit of interlocking plates liquifies into a small icosahedron after being doffed.

While wearing this armor, you gain a +2 bonus to AC. 

While wearing this item as necklace or armor, you are hidden from divination magic. You can't be targeted by such magic or perceived through magical scrying sensors.
Additionally, you can cast the jump spell from it as a bonus action at will, but only targeting yourself when you do so.

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.

Notes: Bonus: Armor Class, Str. 15 Required, Stealth Disadvantage
