Set Shield (combat)
You can use your shield to stop a charging opponent in his tracks.
Prerequisites: Shield Focus, Dex 13
Benefit: You can ready your shield against a charge, much like a spear or trident. If you do, double your shield bonus against a single opponent who charges you before your next turn (you must declare which opponent when you ready the action). You may add your shield bonus (before doubling) to your CMD for overrun or bull rush attacks that opponent makes while charging.
Something about the dramatic movement makes this feat work for me. The classic warrior setting his shield against a terrible blow increases the tension of the moment enormously as one wonders if he can withstand the attack with all his strength and the protection of his shield.
