Weapon

Common

Guard. Guard weapons are made to fight defensively, often designed with a long reach or flat surface for parrying. While wielding a Guard weapon, whenever a hostile creature moves within your reach, and you did not move on your last turn, you can use a reaction to make a weapon attack with a Guard weapon against that creature. If the attack hits, then it deals no damage, the creature immediately stops and its speed becomes 0 until the end of its turn.
Reach. This weapon adds 5ft to your reach when you attack with it, as well as when extending your reach for an Opportunity Attack.
Two-Handed. This weapon requires two hands when you attack with it.
Sword. Once per turn when you attack a creature with a sword, you gain a bonus to your damage roll equal to your prof. bonus if you’ve damaged the target with an attack since the start of your last turn. You don’t gain this benefit if you attack another target during this time. When you attack an object made of rope, vine, or similar material with a sword, your damage rolls deal maximum damage. You only gain this benefit if you are proficient with the weapon.
Slashing. On a critical hit, the target gains the Bleeding condition.

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.

Sword. On a hit, you can forgo 1 extra attack to force the target to make a Dex Save. Failure. The target takes 1 extra die of damage from the attack and the target has DisADV on its next attack roll or ability check before the end of your next turn.
Martial Save DC. (8 + prof. bonus + Strength or Dexterity modifier)
Cleave. On a hit, you can forgo 2 extra attacks to make a wide swing with your weapon and choose a target within your reach. You can make a melee weapon attack against that target and up to 2 targets adjacent to it that are also within your reach. Use the same attack and damage roll against all creatures.
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)
