Striker

To most seasoned war-masters wielding multiple weapons is more style than substance, reserved for street performers and circus acts. Strikers disagree; they hold that within these flashy maneuvers lies an effective fighting style that uniquely blends offensive and defensive capabilities.

Dual Wielder

Your extensive training has provided you with the necessary skills to wield multiple weapons at once. When you choose this martial archetype at 3rd level, you receive the Dual Wielder feat for free.

Dual Weapon Flurry

At 3rd level, when you use your bonus action to make an attack using two-weapon fighting, you can make two bonus attacks instead of just one, attacking with each weapon once. In addition, when you use your Action Surge you gain the ability to strike at an enemy with both weapons at once. Whenever you hit a creature with a weapon attack during your Action Surge and are wielding two weapons, you can deal additional damage to the target as if you had also hit them with your second weapon, using the same to-hit roll as the triggering attack.

Lower Defenses

Starting at 7th level, you can attempt to use your off-hand weapon to temporarily open an opponent's defenses. When you make a weapon attack against a creature on your turn, instead of attacking normally you can make an attack roll contested by the target's Strength or Dexterity saving throw (their choice). If you win, until the end of your turn the target's AC is lowered by an amount equal to your proficiency bonus. You must be able to see the target to use this feature. You can attempt to use this feature multiple times in the same turn, but can only lower a target's AC once per turn. You can use this feature a number of times equal to your proficiency bonus, and regain expended uses when you finish a long rest.

Heroic Grip

At 10th level, when wielding a weapon with the versatile property you can use the two-handed damage die of the weapon even if you are wielding it in one hand.

Improved Dual Wielder

When you reach 15th level, the AC bonus you receive from the Dual Wielder feat increases to +2.

Titanic Grip

At 18th level, you can ignore the two-handed weapon property for melee weapons, and can use two-weapon fighting while wielding one or more two-handed weapons. You can also draw or stow two two-handed melee weapons at once. While wielding a two-handed weapon in one hand, you have disadvantage on attack rolls made with that weapon.
