Specialization: One-Handed Style

The character can use his empty hand as a secondary weapon, using it to punch, Grab Attack, throw, etc. while he is wielding his one-handed weapon.

Normal penalties for using two weapons apply. A character who specializes in the one-handed weapon style of battle gains an AC bonus of +1 when he fights with a weapon in one hand, and no shield or weapon in his other hand. By spending 2 additional proficiencies, the character can improve this AC bonus to a maximum of +2.

If the character is also familiar with the Specialization: Two-Handed Style, and is wielding a weapon that can be used either way, he can switch back and forth at the start of every round of combat.
