Unweave spell:
Syntax: cast 'unweave' <character>                      (Mage Level 6 Spell)
                                                        (Cleric Level 6 Spell)

This spell dispels magical affects on a character.  It may be used as an
offensive spell to remove an enemy's magical advantages, or as a benign spell
to remove a friend's (or one's own) magical handicaps.  Unweaving a spell of
significantly greater power than your own is generally impossible.  The attempt
to unweave another being has several factors affecting it,  leaving the results
slightly variable (sometimes, subsequent castings can produce slightly better
or slightly worse results); when targetting oneself with this spell, the
results prove more consistent.  (Min Mana = 15)
