Bone Armor

The Bone Armor protects its wearer from almost all kinds of physical attacks. It also has the ability to transform into civilian clothing and back at the wearer's convenience.

As the Bone Armor bears the Guillotine Cross symbol, it can be assumed that only Assassins of the Cross wear this particular kind of armor as both Loki and Julianna Lucille are the only ones to have ever been depicted wearing Bone Armor.
