You only need one melee skill, and One-Handed is arguably the superior one, so for the purposes of combat effectiveness, no investment is recommended in Two-Handed. The other advantage of One-Handed weapons is that you can use spells or a shield in your off-hand, or dual-wield, making One-Handed more versatile in essentially every way. The most obvious is the terrible speed of Two-Handed weapons, which is bad enough to make one question whether the damage output is even worth it. Unfortunately, some flaws exist on the combat side of things that make One-Handed weapons a more effective choice. There’s just something majestic about two-handed weapons, and in a game like Skyrim the appeal to be a battle-axe bearing barbarian all the more alluring. Its perks are nearly an exact copy of the One-Handed perks you have perks that decrease Stamina consumed by power attacks, perks that unlock more devastating power attacks, and perks that give different weapon types (greatsword, battle-axe and warhammer) bonus critical damage, bleed damage and armor penetration, respectively.

The Two-Handed Skill Level determines your damage with two-handed weapons.
