Save: Fortitude negates
Spell Resistance: Yes
Area of Effect/Target: Huge (6.67 metre radius)
Duration: Instant
Description: This spell creates a blast of air that knocks down any creatures failing their saving throws. It is also powerful enough to disperse any cloudlike area of effect spells (such as cloudkill) that are in the path of the wind gust. Receives +5 DC for knock down effect at CL20.
Notes
Can also be used to kill various cloud type creatures if it beats their spell resistance and they fail their saving throw.
As it does not have the deafening effects associated with Great Thunderclap it is a good spell to cast and the point of spawning to knockdown targets whilst leaving them vulnerable to Curse Song and Taunt/Persuade effects.
