Capable Hands

Your training in handling weapons in both hands makes you capable of dual-wielding weapons others cannot. Beginning when you take this archetype at 3rd level, you treat all simple one-handed weapons as if they had the light quality in addition to their other properties.

Two-Weapon Tactics

Your pursuit of mastering a variety of arms has provided you with specialized tactics when using a similar weapon in each hand. Utilizing them in compliment of each other, you can create unique opportunities and strategies when engaged in combat. Beginning when you take this archetype at 3rd level, the damage types of the weapons you wield change your stance and style to provide certain benefits:

Bonecrusher: You have learned to put the combined blunt force of bludgeoning weapons to brutish use. When two-weapon fighting with two bludgeoning weapons, a target who is hit by both of your weapons in one of your turns is concussed by the shocking force of the blows. The target suffers from disadvantage on the first ability check or attack roll it makes until the end of its next turn, and the first attack made against it by your allies has advantage until the start of your next turn.

Slice and Dice: With two sharp edges in your hands, you are capable of inflicting bleeding wounds that incur lingering damage on your opponents. When two-weapon fighting with two slashing weapons, a target that is hit by both of your weapons in one of your turns takes an additional 1d6 slashing damage at the start of its next turn. When you reach 10th level in this class, the damage increases to 1d8, and to 1d10 at 18th level.

Twin Fang: You have learned how to utilize the punishing power of piercing weapons to reduce the effectiveness of your opponents. When two-weapon fighting with two piercing weapons, a target that is hit by both of your weapons in one of your turns suffers from a 10-foot reduction in speed and must roll a 1d4 and subtract the result from any ability checks and attack rolls it makes. Both penalties last until the end of the target’s next turn.

Parrying Strike

You have learned how to use your weapons for more than just offensive power. Starting at 7th level, when struck with a melee attack, you can use your reaction to parry the blow with a swing of one of your weapons and reduce the incoming damage. Roll the damage die of the parrying weapon and add half of your fighter level (rounded down); reduce the damage by that amount.

Advanced Two Weapon Tactics

Your skill in creating synergy between your two weapons has grown to include weapons of differing types. Starting at 7th level, you learn the following Two Weapon Tactics, in addition to the ones you knew before:

Hammer and Nail: Combining brutal power with the cruel accuracy of a sharp point, you have learned how to use blunted blows to open windows of attack on your opponent's most vital areas. When two-weapon fighting with a bludgeoning weapon and a piercing weapon, the bludgeoning weapon receives a +1 on weapon attack rolls, and the piercing weapon has an improved critical attack range of 19-20.

Bash and Slash: The fusion of a blunt face with a sharp edge allows for vicious slicing attacks against weakened, bruised opponents. When two-weapon fighting with a bludgeoning and a slashing weapon, the bludgeoning weapon receives a +1 on weapon attack rolls, and the slashing weapon receives a +2 on damage rolls.

Slicing Skewer: The prime example of deadly precision, fusing the power to puncture and cut allows for the opportunity to inflict a variety of wounds with savage accuracy. When two-weapon fighting with a slashing weapon and a piercing weapon, both weapons receive either a +1 to weapon attack rolls or a +1 to damage rolls. This is decided per weapon before each attack roll and can change between multiple attacks with the same weapon.

Sturdy Grip

Time spent in combat wielding two weapons has given you strong hands and a solid grip. Starting at 7th level, you have advantage on any rolls to resist being disarmed and any Strength (Athletics) checks involved with climbing.

Ambidexterity

Your constant use of both hands in combat has allowed you to increase the efficacy of your offhand to rival your main hand. Starting at 10th level, you gain the following benefits while two-weapon fighting, both of which utilize any relevant Two-Weapon Tactics:

• When using a bonus action to engage in two-weapon fighting and attack with a second weapon, you can make two attacks with that weapon instead
• When making an opportunity attack, you can attack with both of your weapons. If the first attack reduces the target's HP to 0, you can make the second attack at another valid target in range
