After using Weighted Strike, regardless of whether you hit or miss your target you send a small shockwave through the ground.
Prerequisite(s): Str 15, Operator Style, Weighted Strike, Base Attack Bonus +5.
BENEFIT
All adjacent creatures must make a Reflex save (DC 10 + half your character level + your Strength modifier) or be knocked prone. If you hit the target of your Weighted Strike, they must make a Fortitude save in addition to a Reflex save. If the target fails one of the saves, they are knocked prone. If the target fails both saves, they suffer the effects of the Awesome Blow combat maneuver and are knocked prone. A successful save against both negates the Awesome Blow and prone effects. Creatures that are one size size category larger than you gain a +2 bonus to the saves of either effect while creatures that are two sizes larger are immune. Creatures that are one size smaller than you receive a -2 penalty to the save of either effect, while creatures two sizes smaller receive a -4 penalty to either effect.
