Two-Handed Combat Expertise is a skill that can be used by human characters. Once trained in this skill, it is always in effect.
Skill Text: "No matter what some may say, combat isn't pretty or subtle. You intend to prove that by swinging about swords long as a troll's arm and hammers so ferocious they can reduce said creature's head to a bloody pulp with one well placed stroke. The advantages in battle are obvious, and more than that: you can never get lost in the woods, for you'll always leave a track of limbs that works even better than the traditional breadcrumbs."
