Help Illusion

The illusions spells are dedicated to deception and trickery.  They
can be used to mask appearances, or create distractions for the
party.  Currently, the illusion group is very small, but it will
be expanded in the future.  Only thieves and mages can cast illusion
spells, which consist of the following:

invis          turns the target invisible
mass invis     turns the caster's group invisible
ventriloquate  allows the caster to put words in someone's mouth
