Brutal Strike

Power Attack (PH) , STR 13, base attack bonus +6,

If you use your Power Attack feat to increase your damage with a bludgeoning weapon, you can attempt a brutal strike. You must declare your intention before making your attack. If the attack hits and your opponent takes damage, he must make a Fortitude save (DC 10 + your extra damage from the Power Attack feat on the attack) or be sickened for 1 round. You can use this feat once per round during your attack action.

This feat cannot be used against a creature that is not subject to extra damage from critical hits. A fighter can select Brutal Strike as one of his fighter bonus feats.

You can batter foes senseless with your mace, morningstar, quarterstaff, or fl ail. Few victims are willing to stand toeto- toe with a warrior known for knocking his foes witless with a single strike.
