Demon Slayer

The Demon Slayer Corps is as an organization dedicated to hunting and killing demons. Most members of the Demon Slayer Corps are combatants, known as Demon Slayers.

As the Demon Slayer Corps isn't officially recognized by the government, its members are forced to work in secrecy, which means that Demon Slayers cannot openly carry their swords in public. The majority of people are unaware of the existence of demons, and even if Demon Slayers were to reveal the truth about their job, they would be met with skepticism and disbelief from most individuals. Allowing Demon Slayers to openly wield swords would only incite chaos and confusion among the general population. By maintaining a low profile and avoid drawing unnecessary attention, they can carry out their duties covertly and effectively. Nevertheless, whispers of the Demon Slayers have permeated public consciousness, existing as mere folklore in the minds of some. However, when civilians encounter demons or witness a Demon Slayer engaging a demon firsthand, they come face-to-face with the reality of their existence and the truth behind the tales they've heard.

Without any support from the government or other sponsors, the Demon Slayer Corps relies solely on the resources provided by the Ubuyashiki family for its daily operations. The Ubuyashiki family's accumulated wealth, acquired through their unique gift of foresight,[6] plays a vital role in ensuring that the Demon Slayers have the necessary means and resources to fulfill their duties effectively.

At 1st level, you have acquired enhanced senses, either through training or other means. You gain advantage on Wisdom (Perception) checks related to a sense of your choice: smell, hearing, or touch.

Total Concentration Breathing

Total Concentration Breathing is a breathing technique which involves expanding one's lungs to intake as much air as possible, accelerating one's blood flow and heartbeat while increasing their inner body temperature, resulting in their bones and muscles becoming more excited.

As an action, you may enter Total Concentration for a total time of 1 minute or until you lose concentration (as if you were concentrating on a spell). To do this you must be able to freely breathe.

While in Total Concentration Breathing you may replace your attack action with one of your Breathing Techniques.

You may enter Total Concentration a number of times equal to your Constitution Modifier (minimum of 1), and regain all uses of this feature at the end of a long rest.

Breathing Style

Breathing Styles are swordsmanship styles that makes use of an esoteric breathing technique known as Total Concentration Breathing practiced and taught by members of the Demon Slayer Corps and are used in combat by Demon Slayers

At 2nd level, you choose a Breath Style. Choose between Water Breathing, Thunder Breathing, Beast Breathing, Serpent Breathing, Mist Breathing, Wind Breathing and Flame Breathing. All Breathing styles are detailed at the end of the class description. Your choice grants you Breathing Techniques at 2nd level and again at 5th, 8th, 11th, and 14th.

Kasugai Crow

Starting at 3rd level, you gain the service of a crow sent by the Demon Slayer Corps to watch over you. The crow assumes the form and game statistics of a raven, and it always obeys your commands, which you can give telepathically while it is within 100 feet of you.

While perched on your shoulder, the crow can’t be targeted by any attack or other harmful effect; it can’t take damage; and it is incapacitated.

The crow speaks and understands the same languages you do.

In combat, you roll initiative for the crow and control how it acts.

The crow doesn’t require sleep. While it is within 100 feet of you, it can awaken you from sleep as a bonus action.

The crow vanishes when it dies, if you die, or if the two of you are separated by more than 5 miles.

At the end of a short or long rest, you can call the crow back to you—no matter where it is or whether it died—and it reappears within 5 feet of you.

Abillity Score Improvement

When you reach 4th level, and again at 7th, 10th, 13th, 16th and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1.

Trained Breathing

Thanks to the effort and training for full concentration breathing your lungs are now stronger than ever. Beggining at 6th level you can maintain your Total Concentration Breathing for up to 1h at a time, and during this time you have advantage on Strength checks and Strength saving throws.

You also can hold your breath for twice as much time as you could previously.

Extrassensory Perception

Extrasensory Perception grants the user a "sixth sense" which enables them to sense the paranormal or supernatural. Most Demon Slayers, are able to sense the presence of demons from an extreme distance.

As an action, you can open your awareness to detect such presences. Until the end of your next turn, you know the location of any undead, fiend or monstrosity within 60 feet of you. You know the type of any being whose presence you sense, but, unless you have met this creature before, not its identity. Within the same radius, you also detect the presence of any place or object that has been fiddled with by such creatures.

You can use this feature a number of times equal to 1 + your Wisdom modifier. When you finish a long rest, you regain all expended uses.

Total Concentration Breathing: Constant

Total Concentration: Constant is a Total Concentration Breathing state during the morning, noon, and night, and even while asleep that advanced Demon Slayers, can constantly maintain. There is an immense difference in strength, speed, and stamina between someone who can maintain Total Concentration Breathing at all times and someone who cannot. By doing it every minute of the day, one's physical fitness drastically improves.

At 12th level you can maintain your Total Breathing Concentration for an indefinite amount of time. You also receive advantage for maintaining your Total Concentration.

Recovery Breathing

At a more advanced level, Total Concentration Breathing is also capable of slowing down the circulation of poison in the bloodstream and even clotting wounds from severe injuries. By focusing on every inch of the body and raising the accuracy of one's Breathing, one can spread their sensitivity throughout one's body and detect and even heal hidden internal wounds they may have.

At 12th level while you are concentrating in your Total Concentration Breathing and below half of your hit point maximum, you can as a bonus action, recover 1 + your Constitution Modifier of hit points or end an effect on yourself that is causing you to be poisoned.

Slayer Mark

Demon Slayer Marks are irregularities on the skin that resembles a birthmark and which commonly appears on the face or another visible location of the body of Demon Slayers that resemble the crests of demons. Each Demon Slayer possesses a unique pattern to their Mark which appear to be based on the Breathing Style they utilize. The Mark can only be awakened under very specific conditions and grant special abilities while also enhancing pre-existing traits of the bearer. Once awakened, the Mark can disappear after a period of time along with its effects, though it can be re-activated by meeting the same conditions.

Starting at the 15th level, your Slayer Mark manifests itself on your body after the following conditions are met:

• Your current hit points needs to be below one third (rounded down) of your hit point maximum
• You must not be affected by any harmful conditions
• You must be in the middle of combat
• You must be concentrating on Total Concentration Breathing

You can choose the color, shape and placement of your mark on your body. While your mark is manifested you recieve the two following benefits:

• You may use two different Breathing Techniques in a single attack action.
• You gain resistance to bludgeoning, piercing and slashing damage.

When you exit your marked state you must succeed on a Constitution Saving Throw of DC20 or become paralyzed until the end of your next turn.

Crimson Red Blade

Normally, a demon slayer’s swords come into virtually any color dependent on the material and their Breathing Style. However, there is one color that cannot be normally accessed: a shining bright red. Unlike other colors, a bright red sword has special properties and can only be accessed by Demon Slayers who have awakened the Demon Slayer Mark. Moreover, any sword can become bright red regardless of the blade's original nature. However, the blade can only stay bright red for a certain amount of time before returning to normal. The bright red hue that envelops the blade is achieved through deliberate actions intended to raise the blade's temperature, fueling the conversion of mechanical energy into thermal energy.

Beginning at the 17th level, while in your marked state, you may use your action to turn any non-magical melee weapon you are wielding into a Crimson Red Blade. While the weapon is a Crimson Red Blade it receives the following traits:

• It becomes a +3 weapon of any type it were previously
• Any breathing techniques made using this weapon now deal radiant damage.
• A creature hit by an attack made by this blade reduces it’s hit point maximum by the amount of damage it received on the attack. If a creatures hit point maximum is reduced to 0 by this weapon, it is disintegrated and can only be revived by nothing short of a Wish Spell.

The weapon stays as a Crimson Red Blade for 1min, until your marked state ends or if you let go of the weapon. The weapon is destroyed when its Crimson Red state ends.

Transparent World

Demon Slayers that have awakened the Mark can utilize a special form of ocular extrasensory perception that alters their vision, allowing them to perceive other living beings as if they were transparent, only being able to see the inner workings of their bodies.

Beginning at the 18th level, you may as a bonus action enter the Transparent World for 1min. While on the transparent world you can determine how physically well a creature is, thus allowing you to know how many hit points a creature has remaining. You also receive advantage to all checks made to understand a creatures nature, mannerisms, feelings and thoughts.

You may use this a number of times equal to you Wisdom Modifier (minimum of 1), and regain all uses of this feature at the end of a long rest.

Anata

The Anata is an esoteric and mysterious state of being in which one completely erases their presence, will to fight, bloodlust, anger, hatred, malevolence, drive and animosity. Once in this state, the user's behavior becomes incredibly tranquil and focused, often being compared to that of a plant. Although it does not enhance one's own combat prowess, it is implied to be regarded as the highest state of physical combat one can achieve.

At the 20th level, when you begin your Total Concentration Breathing you can choose to instead enter a state of Anata. While in your Anata state you receive all benefits related to your Total Concentration Breathing but it does not require concentration. Additionally, for all effects considered by you as harmful, you are considered an object and you can’t be detected or seen by any special senses (such as Darkvision, Truesight and Tremor Sense)

While in your Anata state you can’t speak nor understand any spoken languages, you immediately fail any Intelligence saving throws and immediately succeed any Wisdom Saving throws.

You may end the Anata state at any moment by using a bonus action. You can use this feature only once per long rest.

Breathing Styles

All known Breathing Styles currently taught within the Demon Slayer Corps are derived from Sun Breathing, the first one ever created. The majority of known Breathing Styles mimic a certain element of nature and replicates it with the user's movements, techniques and abilities.

New Breathing Styles are always being created to suit a Demon Slayer's combat needs, which results in new weapons being utilized in demon hunting. Such Breathing Styles embody a bigger variety of concepts, like animals, plants and emotions. When utilizing a Breathing Style, users automatically visualize themselves manipulating the subject behind their style, making it seem as if they were using magic, though those that are less apt and proficient in their style will visualize less of it than one who is.

Water Breathing

Water Breathing is a Breathing Style that mimics water, specifically the flow, flexibility and adaptability of the liquid and replicates it with the user's movements, techniques and abilities. Most, if not all, known techniques involve the user bending their body, arm and weapon in a fluid motion to match the movements of rushing or flowing water. Users also visualize themselves seemingly creating and manipulating water when unleashing its techniques.

3rd, 4th and 5th forms:

5th level Water Breathing techniques

It is a “sword strike of kindness” used when the enemy willingly surrenders. You make a melee weapon attack against a creature within the weapons range, this attack only hits if the targeted creature willingly accepts to take it. This attack is an automatic critical hit and deals double the damage it normally would, as if the targeted creature is vulnerable to it. When you attack a creature that has at least one head, you cut off one of the creature's heads. The creature dies if it can't survive without the lost head. A creature is immune to this effect if it is immune to slashing damage, doesn't have or need a head, has legendary actions, or the GM decides that the creature is too big for its head to be cut off with this weapon. Such a creature instead takes an extra 6d8 slashing damage from the hit.

While falling from a height greater than 10ft, make a melee weapon attack directed at a creature within range of the weapon directly below you. On a successful hit, you deal an additional 3d10 slashing damage and you ignore half of the total fall damage you would have taken from falling.

The damage die used in this technique becomes a d12 if the target is an undead, fiend or monstrosity.

11th form

14th level Water Breathing technique

At 14th level you learn the final and most potent defensive technique of the Water Style.

• Dead Calm The user ceases all body movements and enters a state of complete tranquility, deflecting, blocking and cutting any incoming attacks with imperceptible speed with their blade. However, its effectiveness is limited as fast and numerous attacks can break through.

You then make a melee weapon attack against a target within the weapon’s range. On a successful hit, you deal an additional 8d10 slashing damage. If the target is an undead, fiend or monstrosity, it also becomes blinded until the end of its next turn. The rebound you suffer from this technique is so great you become stunned until the start of your next turn.

Beast Breathing

Beast Breathing is a Breathing Style that mimics beasts/wild animals, specifically their unpredictable, ferocious and wild nature, including movements, attacks and senses, and replicates it with the user's movements, techniques and abilities.

Until the end of your next turn, if any sort of damage would drop you to 0 hit points, you drop to 1 instead.
• Whirling Fangs The user rapidly spins their swords in a circular motion, deflecting enemy attacks such as projectiles.

Jump up to 20ft directly upwards, then make one melee weapon attack against each creature within a 20ft cone pointed directly downwards, that originates from you. On a successful hit, you deal an additional 3d8 slashing damage and the target is pulled in a straight line toward the center of the sphere, ending in an unoccupied space as close to the center as possible (even if that space is in the air).

Flame Breathing

Flame Breathing is a Breathing Style that mimics flames and replicates it with the user's movements, techniques and abilities. Most, if not all, known techniques and forms involve extremely powerful singular strikes which 'burn' their opponents, with most attacks being initiated from a high stance. Users of Flame Breathing also visualize themselves seemingly creating and manipulating fire when unleashing its techniques. Due to the passing of time and of the last user of this breathing, some forms have been lost, never to be remembered again. Although, the sheer impact and influence it’s last user shared with his philosophy in battle, affected the way one teaches this style of fighting, from a mainly offensive technique to a supportive and defensive one, that focuses on enhancing and defending others.

Interception

Beginning at 5th level when a creature you can see hits a target, other than you, within 5 feet of you with an attack, you can use your reaction to reduce the damage the target takes by 1d10 + your proficiency bonus (to a minimum of 0 damage). You must be wielding a shield or a simple or martial weapon to use this reaction.

Tunnel Fighter

Starting at 11th level, as a bonus action, you can enter a defensive stance that lasts until the start of your next turn. While in your defensive stance, you can make opportunity attacks without using your reaction, and you can use your reaction to make a melee attack against a creature that moves more than 5 feet while within your reach.
