Thunderclap (Drd 4)

   Thunderclap is used to create a loud noise
and damage creatures. The spell creates a sudden disappearance
of all non-magical air/gas in the affected area for a fraction
of a second. After the spell expires the air rushes back in
causing the thunderclap.

   Individuals in the area of effect take
1d10 points of damage from the thunderclap. They will also
be stunned for one round and deaf for 1d4+1 rounds unless
they make a fortitude save. Air-based creatures in the area
take 4d10 points of damage. All non-magical flames are blown
out in the area. The thunderclap can be heard for 2 miles
from its center.
