Only a chosen few truly master the complicated art of fighting with two weapons. The character is now among that elite company, able to wield full-sized weapons in both hands. Characters with this ability have their fatigue permanently reduced by -2.5% when dual-wielding.
Characters with this talent will see "Main-Hand" weapons listed as "One-Handed," and can equip in either hand.
Because of the way this talent is implemented, it reduces the fatigue costs of all talents while the character is wielding two weapons – not just those talents from the Dual Weapon chain as the description implies. As a result, talents such as Taunt or Perfect Striking will consume less stamina when wielding two weapons. This is due to how abilities are defined and referenced in the various GDA files and not necessarily a bug.
Due to how combat mechanics work, this skill could be less useful than it appears. When wielding small one-handed weapons (daggers), a character benefits from adding their Dexterity to damage, but when these are switched out for full-sized weapons, a character must rely on Strength. Therefore, a character will have to invest 36 points into Dexterity, then invest into Strength, making them dependent on multiple attributes simply for the benefit of the slight damage increase that larger weapons offer.
