Body Alterations -defensive
Armor:
One of the rarest powers, armor is a full-body suit of condensed bone plates. Its weight makes it very uncommon for shinobi since it pretty much makes them as agile as a turtle. On the other hand it makes them just as tough to kill. The very few masters of this power can activate only parts of the armor, thus retaining some of their agility. Flight is impossible with more than 25% of the armor activated.
Mutations: Spikes or bladed arms.
Shield:
The shield is a well known ability. It usually manifests as a mass of bone in a more or less circular shape on the left hand. Experienced users can activate and deactivate this power in an instant, enabling them to attack with their left hand unhindered, while being ready to defend. Masters of the shield power have been known to use it for slamming an enemy or counter attacking under cover of it.
Mutations: Known mutations include spikes on the shield or even blades on the edges.
