Usage:
harvest spellcomps <corpse>

This skill allows a necromancer to extract spell components from fresh
corpses.  This skill is really only useful if you have or know someone
who uses one of the 'brew potion' skills or when used with the
spell 'Gisco's gib grenade.  The spell components themselves are
nasty and short lived, but certain brews can only be produced using them.

If you are well-versed in 'undead lore', you can harvest spell
components from the bodies of corporeal undead.

Use the 'harvest' command to harvest spell components from fresh
corpses to use the skill.
