Format:
cast 'animate dead' <target>            cost: 21 mana

   The animate dead spell animates a corpse with magic.  The corpse (zombie)
will then follow the caster about until either killed or the magic dissipates.
Zombies will follow orders.

   The most common use of this spell is for corpse retrievals, as the zombie
will be carrying all the equipment that was on the original corpse.
