You've mastered balancing the weight of a heavy weapon, using it expertly in combat. You gain the following benefits:

• You can wield a two-handed weapon in one hand, if you choose to dual-wield great weapons you must have proficiency in the weapons utilized.
• You can use two-weapon fighting in this way, even when the one-handed melee weapons you are wielding are heavy.
• You gain a +1 bonus to AC while you are wielding a separate melee weapon in each hand. If the weapons you are wielding are of the heavy type then you take a -1 to your AC as you are burdened by their weight.
