Thunderclap

Thunderclap is a regular-type Sound spell that produces a single, very loud sound, typically the crash of thunder. The "subject" is merely a spot you choose as the spell's center. Outdoors, anyone within three yards of the spot can be deafened (HT resists), the effect of which can take hours to cover (HT each hour). 
In an enclosed area (such as most dungeons, or rooms less than 30' or so), this "deafening range" increases to six yards. The caster resists their own thunderclap at +2 to HT. 
* Duration: Instantaneous. Deafness lasts until victim(s) recovers.
* Cost: 2. Cannot be maintained.
* Prerequisites: 
** Clerical: PI 1
** Druidic: PI 1
** Wizardly: Sound
== Tactics ==
While Druids tend to be pretty healthy characters who might shrug off this effect, Clerics and Wizards should probably cast Resist Sound on themselves before blasting an area with this spell.
== As a Prerequisite ==
* For wizards, Thunderclap is a prerequisite to the more powerful, stunning spell, Concussion, as well as the "megaphone spell", Great Voice.
