Shout

When a shout spell is cast, the magic-user empowers himself or herself with tremendous vocal powers. 

Via the dweomer of the spell, the caster releases an ear-splitting noise which has a principal effect in a cone shape radiating from the mouth of the caster to a 3" terminus. 

Any creature within this area will be deafened for 2-12 rounds and take a like amount (2-12 points) of damage (un-less a saving throw is made). 

Any exposed brittle or similar substance subject to sonic vibrations will be shattered by a shout, e.g. a wall of ice. 

A spell of this nature can be employed but once per day, for otherwise the caster might permanently deafen himself or herself. 

The material components for casting the shout spell are a drop of honey, a drop of citric acid, and a small cone made from a bull's or ram's horn.
