Single-Handed

You have trained to have exceptional balance, might, or force of personality, making you devastatingly versatile even with weapons of considerable size. You gain the following benefits:

• Increase one Ability score by 1, up to a maximum of 20. This score should be the primary Ability used in your melee attacks (Strength, Dexterity, Charisma, etc), but does not have to be.
• You are able to wield a melee weapon with the two-handed property in one hand, provided you are not wielding another weapon in your other hand. The weapon’s effectiveness is diminished, decreasing by one damage die (2d6/1d12 decreases to 1d10, for instance, 1d10 to 1d8, 2d4/1d8 to 1d6, etc.), as would be a versatile melee weapon wielded in one hand.
