Saving Throw: None
The ground around you trembles, knocking down anything in its path.
Each creature in the area must make a DC 15 Balance check or be knocked prone.
If you are underground, each creature takes 1d6 points of nonlethal damage from falling debris, regardless of whether they make the Balance check.
Enhance: You can enhance this incantation in one or both of the following ways.
For every 1 point by which you increase the DC, the Balance DC increases by 1 point.
If you increase the DC by 4 points, you can channel this incantation as an aura, forcing each creature in the area to make a Balance check at the beginning of each round.
