Usage:
cast bone arrow <options>

The bone arrow spell is similar to bone blade, allowing necromancers to
magically combine a drop of their blood and a harvested tooth into several
projectiles of dense bone. The bone projectiles can then be fired from a
ranged weapon. Ammunition so made will only last for a few shots before
shattering.

The default projectile created by the spell is an arrow, though the caster
can specify bolt, dart or bullet to create ammunition for crossbows,
blowguns or slings, respectively.
