cast 'chain lightning' <target>         cost: 33 mana

   Chain lightning is an extremely high level mage spell.  Rumor has it that
this spell produces a high-energy bolt of lightning that randomly jumps and
arcs from person to person, hitting everything in the general area.

   To learn and cast this spell takes a vast amount of knowledge of lightning
and electricity.  As such, without the proper background, you will be unable
to use this spell.  It is suggested that the caster at least be familiar with
casting 'ball lightning' before attempting this spell.

WARNING: This spell can be very dangerous when used in public places.  Any
innocent lives that are lost will be considered player kills, and will be
treated as such.  This spell is heavily logged to provide enforcement of
this rule.
