Weapon

Common

Aquatic. You do not have DisADV on attacks made using aquatic weapons as a result of being underwater.
Light. A light weapon is small and easy to handle. You can use either your Strength or Dexterity modifier for both the attack and damage rolls.
The Finesse property has been combined with the Light property. Anything that would require Finesse (like the Rogue Sneak Attack feature) and any weapon that uses Dexterity for its attack and damage rolls works with this property.
Range. A weapon that can be used to make a ranged attack has a range shown in the table. The range lists two numbers, the first is the weapon's normal range in feet, and the second indicates the weapon's long range. When attacking a target beyond normal range, you have DisADV on the attack roll. You can't attack a target beyond the weapon's long range.
Thrown. If a weapon has the Thrown property, you can throw the weapon to make a ranged attack. If the weapon is a melee weapon, you use the same ability modifier for the ranged attack and damage rolls that you would use for a melee attack with the weapon.
Thrust. When you attack a creature with a thrust weapon, you gain a bonus to your damage roll equal to your prof. bonus if the target is Impaired, Prone, or Mounted on a creature no more than one size larger than you. You only gain this benefit if you are proficient with the weapon.
Piercing. On a critical hit, the target becomes Impaired until the end of your next turn.

Martial Special Attacks

When you land any attack in combat you can choose to make it a Special Attack by expending one of your extra attacks. The additional bonuses below are either added immediately to the attack you just landed for extra effects OR expended before you make the attack for ONE all-in strike.
Each of these Martial Special Attacks have certain requirements and if the target needs to make a save, it's always against your Martial Save DC.

Thrust. When you make an attack, you can forgo 1 extra attack to lunge with your weapon. The reach of the attack is increased by 5ft and it deals 1 extra die of damage.
Feint. When you make a weapon attack, you can forgo 1 extra attack to make a Deception Check vs the target's Insight Check. Success. You gain ADV on your attack roll and deal 1 extra die of damage on the attack.
Martial Save DC. (8 + prof. bonus + Strength or Dexterity modifier)
Stagger (Combo). On a hit, you can forgo 1 extra attack to force the target to make a Con Save. Failure. The target becomes Vulnerable to the next source of Slashing, Piercing, or Bludgeoning damage before the start of your next turn. You can only do this once per combat.
Martial Save DC. (8 + prof. bonus + Strength or Dexterity modifier)
