Syntax: cast 'chain lightning'  

Chain lightning is a useful spell to a solitary warlock surrounded by
enemies, but any warlock accompanied by allies should be careful in casting
this, lest his friends take more damage than those he intended to harm. The
spell can be cast into an adjoining room to target the people therein.
