Valar Morghuils my good friends.

A League of Assassins with extraordinary skills, the Faceless Men serve the Many Faced God, which is the name they have given to the various incarnations of Death found in various religions. Through training and the use of their Ki, the Faceless Men can not only steal someone's face and identity, but can overcome the limitations of the human body to do amazing things. Living in the House of White and Black, some Faceless Men choose to take the difficult road of leaving and becoming adventures. They take the lessons and skills that they have been taught and apply them to this new life.

Assassin's Blow

Starting at 3rd level, when you hit a creature with an unarmed strike, you can expend a number of ki points to directly attack your target's weak spot and deal additional damage. The extra damage uses your Martial Arts die and for every ki point you expend, you roll that number of dice, to a maximum of 3 ki points.

The maximum number of ki points you can expend increases at 11th level to 4 ki points and at 17th level to 5 ki points.

Tools of the Trade

Your training in the House of White and Black involved many different types of weapons that you have grown familiar with. At 3rd level, you gain proficiency in the use of rapiers and scimitars.

Wearing Another's Face

The Faceless Men's greatest ability is not only to be able to imitate another, but to steal their entire persona. At 6th level, you can take 10 minutes and expend 3 ki points to channel your ki, along with alchemical substances, to take on the persona of someone that you have killed. This ability may only be used to impersonate humanoids that are the same size as you.

You gain not only their face that your may now "wear" but also that person's height and weight, voice and all their memories, though none of their secrets. A person that is actively examining you may make a Wisdom (Insight) check contested by your Charisma (Deception) check. You gain a +5 bonus to your check. This ability lasts until your take a long rest or you end this ability early, furthermore you can only use the same 'face' once every seven days.

Control Your Senses

You have moved beyond the need to rely solely on your sight to engage in battle. All of your senses have been heightened and you can use them in ways that others cannot. At 11th level you now have Blindsight within a radius of 20 ft.

Vanish

You are at the height of your powers and can seemingly move so fast when you strike, that you disappear, only to reappear and attack your opponent without warning. At 17th level, when you take the Attack action you may expend 5 ki points to teleport up to 30 feet and attack an opponent. You have advantage on your attack roll and it deals an additional 2d8 damage necrotic damage as your ki saps at their strength. You can only use this ability once per round.
