Usage:
cast bone armor <yourname>

The 'bone armor' spell is used by necromancers to create very sturdy
protective bone armor.  The armor sprouts from the caster's body, and
the spell is known for being particularly gory and painful.

This spell requires teeth to cast.  The teeth are triggered with an
invocation then swallowed, and the armor forms inside the body before
bursting through the torso to harden into its final form, displacing
anything worn on the caster's torso.

Once in place, bone armor cannot be removed. It will enventually
lose cohesion and fall off.
