Depending on their size, creatures can be knocked down by winds of high velocity (see Table 3–24: Wind Effects). Creatures on the ground are knocked prone by the force of the wind. Flying creatures are instead blown back 1d6×10 feet.

1 The siege weapon category includes ballista and catapult attacks as well as boulders tossed by giants.
2 Flying or airborne creatures are treated as one size category smaller than their actual size, so an airborne Gargantuan dragon is treated as Huge for purposes of wind effects.
Checked: Creatures are unable to move forward against the force of the wind. Flying creatures are blown back 1d6×5 feet.
Knocked Down: Creatures are knocked prone by the force of the wind. Flying creatures are instead blown back 1d6×10 feet.
Blown Away: Creatures on the ground are knocked prone and rolled 1d4×10 feet, taking 1d4 points of nonlethal damage per 10 feet. Flying creatures are blown back 2d6×10 feet and take 2d6 points of nonlethal damage due to battering and buffeting.
