Psionicsts are not limited to attacking single targets. One method of
attack that can affect more then one target is a psychic 'shout.' This
involves the caster, creating with his mind, a large burst of mental
energy that is released into surroundings. This mental energy attacks the
mind of anyone who happens to be in the target area. This spell is refered
to as a 'shout,' due to the loud verbal command needed to execute this
spell. Once the command is uttered, the effects are instantaneous, making
it seem like the verbal command, or shout, is the cause of the damage to
the targets, not the mental portion of the spell.
