You have a +2 bonus to AC while wearing this armor.  Armor assumes shape of wearer and changes form with user (polymorph, beast mode, ext. ext.)

Made of interlocking metal rings, a chain shirt is worn between layers of clothing or leather. This armor offers modest protection to the wearer's upper body and allows the sound of the rings rubbing against one another to be muffled by outer layers.

Notes: Bonus: Armor Class, a custom made shirt made for Zeus by Hephaestus, Combat, Warding
