'chain lightning'
Syntax: cast 'chain lightning' <target> Chain lightning is a deadly spell, producing a powerful bolt of lightning that arcs from target to target in the room, until its force is fully expended. This spell will hit any and all valid targets in the room in order to continue the chain, while the caster him/herself will not be struck unless no other viable target remains. Chain lightning is most effective when used on groups of creatures. See showskill chain lightning for more details.
