[Spells help]  spear of faith                                           
Syntax: cast 'spear of faith' 
Spear of faith calls down the wrath of a priest's god against those of an
opposite aura.  Priests with more experience tend to recite the rituals
necessary with more accuracy, thus their god will intervene to a greater
extent, causing more damage to be done.  The gods are not fools, however,
and those who fall out of favor with their deity often find themselves the
target of this wrath when they attempt to use it.
