Usage:
cast skeletal spider

This low level necromancer cantrip is one of the first spells to make
use of harvested teeth.  The spell forges a tooth into an animated
spider, which can be helpful in combat by attacking or distracting
enemies.  While the spiders aren't particularly powerful, it is
possible to create quite a few of them to create chaos in battle.

At higher levels, skeletal warriors would typically be created
instead, as they are more dangerous and much hardier.
