Demon Slayer

A Demon Slayer trains for many years before going to compete in the final selection, a competition where trainees are released into a demon infested forest. Those who survive become official Demon Slayers. To help level the playing field, many members of the Demon Slayer Corps practice a form of breathing technique, where one channels energy of a certain type (water, fire, etc.) into their sword to perform more powerful attacks.

Breathing Style

At 3rd level, you may choose a breathing style. There are fourteen different known styles which you can choose from, each with their different unique forms. You gain breathing points (BP), which you can spend to use these forms. For every three demons you kill in a battle, you regain 1 of these points. These points are also restored upon a short or long rest. The maximum amount of BP you have is equal to your fighter level + your proficiency bonus. Additionally whenever you kill a creature with a form, it decapitates them.

Flower Breathing:

This form is used by the late flower hashira, Kanae Kocho and her adoptive sister, Kanao Tsuyuri. There is little known about it and its first and third forms are unknown. Due to being a user of the flower breathing technique, you can cast goodberry once per day.

Second Form: Honorable Shadow Plumb (1 BP). As a reaction, the user slashes through the air several times to deflect attacks. The user increases their AC by 3 until their next turn, and all melee attacks against the creature gain disadvantage until the end of that turn. At 10th level, the disadvantage applies to ranged attacks.

Fourth Form: Crimson Hanagoromo (3 BP). As an attack, the user twists while slicing to hit all surrounding enemies. All enemies within ten feet of you must make a Dexterity Saving Throw (DC: 8 + Your Dexterity + Proficiency Bonus) or take double damage from the melee weapon you are currently holding. At 12th level, the damage done by this move increases to triple the damage from your melee weapon.

Fifth Form: Peonies of Futility (8 BP). As an action, the user slashes rapidly at an enemy wish attacks moving so fast that the user's arms are a blur.

Sixth Form: Whirling Peach (3 BP). After a creature misses you with a melee attack, you may use your reaction to spin towards a target within 30 ft. of you to make a melee attack. This doesn't trigger opportunity attacks. Your melee attack deals an 1d8 force damage. At 12th level, the range of this attack increases to 45 ft.

Final Form: Equinoctial Vermilion Eye (9 BP). This technique increases your speed drastically as everything else appears to move in slow motion. You can use a bonus action to activate this ability. You gain an extra turn, your movement speed increases by 15, and can make an additional melee attack on both of your turns. However, the speed at which blood rushes through you can burst your fragile eyes. When you finish your extra turn, roll a d20. On a 1, you lose sight in both eyes and your perception and passive perception scores decrease by 5. You only need one eye to activate your abilities. This goes without saying, but losing both of your eyes makes you go blind. At 18th level, once you lose one eye, you can't lose the other.

Insect Breathing:

Insect Breathing was created by the insect hashira, Shinobu Kocho. This form was created to compensate for the hashira's weak strength by mixing quick lethal strikes with a deadly poison. Upon choosing this breathing style, you learn how to create wysteria poison, which is harmless to non-demons but deals 1d8 damage to demons and the demons must make a DC 15 constitution saving throw or be poisoned. The poison requires 10 minutes of foraging to find the plant and 10 minutes to create one vial of the poison. The poison lasts for 1 hour once applied.

On a hit, the target must make a Dexterity saving throw (DC: 8 + Your Dexterity Modifier + Your Proficiency Bonus) and on a failure, it immediately dies if it has less than 100 hp. If it has more than one hundred hp, it takes an extra 10d8 poison. If it succeeded, it takes an extra 5d8 poison damage. At 18th level, a successful saving throw deals 10d8 damage instead of 5d8.

Sound Breathing:

The creator and only known user of this form is Tengen Uzui, the sound hashira. There are 5 total forms and 3 known ones. Tengen uses an abnormal fighting style, using two short, thicker blades attached by a chain to hit his targets while throwing bombs to distract and stun the enemy. Members of the sound breathing technique can buy bombs for 10 gp each which arrive 1d4 days later. These bombs are 1 inch in diameter and are ranged weapons with the properties 30/90. Hitting an enemy directly deals 2d6 fire damage and all surrounding creatures within a 15 ft. cube surrounding the bomb (including an enemy that was hit) must make a Dexterity Saving throw (DC: 8 + Your Proficiency Bonus + Your Dexterity Modifier) or take 2d6 fire damage on a failed save and half as much on a successful one. Also, you must use a pair of blades attached by chains to use any of the sound breathing forms. The swords count as one weapon that deals 2d6 slashing damage, has a reach of 5 ft., and has the finesse property. Alternatively, you can hold on to the end of one of the swords to increase its reach from 5 ft. to 10 ft. but decrease its damage to 1d6.

First Form: Roar (3 BP). The user raises their swords before slamming them into the ground. The user casts thunderwave at 2nd level (DC: 8 + Your Proficiency Bonus + Your Dexterity Modifier).

Fourth Form: Constant Resounding Slashes (1 BP). The user begins spinning their chained blades around them as a reaction to being hit by an attack to ward it off. After being hit by an attack, the user can use this form as a reaction to increase their AC by 3, potentially causing the attack to miss. If any attack were to hit you before the start of your next turn, increase your AC by 1, potentially causing it to miss. This increase in AC lasts until the start of the user's next turn. At 5th level, the initial increase in AC starts at 4 instead of three. At 10th level, if an attacker hits you with a critical hit while using this move, you may make a melee attack against them if they are in range or throw a bomb if they are in range of the bomb.

Fifth Form: String Performance (8 BP). The user holds the chain blades so that each blade is on a different side of the body before spinning them and charging. As an action, the user may rush in a line up to 60 ft. in length that is 5 ft. wide. The closest creature to the user must make a Dexterity Saving throw (DC: 8 + Your Proficiency Bonus + Your Dexterity Modifier) or take 4d6 slashing damage and be pushed by the blades on a failed save. On a successful save the creature takes half damage and is not pushed. If the first creature succeeds its saving throw, the next creature must also make the Dexterity save or be pushed. If it succeeds it moves on to the next creature.  The creature automatically fails if it is 5 ft. or less from the user when the move is started. If a creature fails, but there are creatures behind it on the line, the creature behind the one being pushed takes 2d6 slashing damage and is pushed 5 ft. to the left or right of the line. A creature being pushed takes 2d6 slashing damage for each 5 ft. traveled. At 13th level, once you have finished pushing the creature, you can make a melee attack with both of your blades that deals an extra 1d6 damage and launches the opponent 25 ft. into the air on a hit. At 17th level, after launching the opponent 25 ft. into the air, you can throw one of your bombs (if you have one) into the opposing creature. It automatically hits if you choose to do so.

If a creature is standing within reach of the user and in the line, the user may make a melee attack against that creature. This move can also be used as a reaction to deflect arrows. As a reaction, the user may spend 1 BP in response to being hit with a ranged attack. The user rolls a d4 and adds their Dexterity modifier to it, then adds the sum to their AC. The bonus to AC only applies to ranged attacks and the increase in AC may cause the attack that triggered this reaction to miss. This bonus to AC lasts until the start of the user's next turn. At 10th level, when the user uses this move as a reaction, they may cause a strong wind to blow in a 60 ft. long 15 ft. wide line.

At level 15, the cube grows from 15 ft. long to 20 ft. long.

Stone Breathing:

Stone breathing was one of the first forms of breathing created. After one of Yoriichi's students failed to replicate the Sun breathing form, Yoriichi worked with him to create a style that best suited his strengths and weaknesses. Thus, stone breathing was created. Stone breathing uses the ground and earth to create a mix of offensive and defensive attacks. There are 5 forms.Its most notable user is the stone hashira, Gyomei Himejima. The stone breathing form can only be performed by using a flail attached to an axe by a chain. This weapon has the two handed properties, finesse, and a reach of 15 ft. When attacking, you can either choose to deal 1d10 slashing damage by using the axe or deal 1d10 bludgeoning damage by using the flail. Due to being a user of the stone breathing technique, you cannot be moved against your will.

First Form: Serpentinite Bipolar (4 BP). The user flings their axe and spiked flail towards the enemy while spinning the chain they're attached by. This causes the axe and flail to spin rapidly making them drill into the enemy on conflict. As an action, the user may make 2 melee attacks, one with the flail and one with the axe, against a creature within 20 ft. of the user. The creature must make a Strength Saving throw for each weapon that hits (DC: 8 + Your Proficiency Bonus + Your Dexterity Modifier) to resist the drilling motion from these attacks. On a failed save, the creature takes 2d10 piercing damage for each failed save, and half as much on a successful one. At 8th level, the drill deals 3d8 piercing damage instead of 2d10. At 13th level, the attack range increases to 30 ft.

Second Form: Upper Smash (3 BP). The user swings the flail and axe at the enemy in a pincer motion before stepping on the flail's side of the chain to make it smash down on the ground before flinging it downward at the target when it rises up. As an action, the user may target a creature within 20 ft. of itself. The user can then either attempt to hit the creature with the axe or feign an attack with the axe to gain advantage with the flail attack. If the user attempts to hit with the axe, then the user may make a melee attack with the axe and the flail. If the flail hits it deals an extra 3d8 bludgeoning damage. If the user attempts to feign with the axe, then they may make a melee attack against the creature with the flail. The attack has advantage and on a hit, it deals 2d10 extra bludgeoning damage and the target must make a Strength saving throw (DC: 8 + Your Proficiency Bonus + Your Dexterity Modifier) or be knocked prone. At 7th level, attacking with the axe deals an extra 1d8 slashing damage. At 12th level, attacking only with the flail deals 3d10 bludgeoning damage.

The user may also choose 1 creature in the cone and make 2 melee attacks against them, one with the flail and one with the axe. Each attack deals an extra 2d6 bludgeoning or slashing damage depending on what weapon they are hit with. If the creature is prone, both attacks automatically are critical hits. At 9th level, each attack deals an extra 1d10 bludgeoning or slashing damage depending on which weapon hits. At 14th level, failing the dexterity saving throw results in taking 4d6 bludgeoning damage instead of 3d6.

Fifth Form: Arcs of Justice (6 BP). The user swings their axe towards the enemy and follows up by swinging their flail while they are caught off guard. Then a barrage of attacks follows to pulverize the enemy. As an action the user may make a melee attack using the axe against a creature within 15 ft. of them. The user may then attack the same creature with the flail, and they attack with advantage if the axe hit. If the flail hits, the creature must make a Strength saving throw (DC: 10 + Your Proficiency Bonus + Your Dexterity Modifier) or be knocked prone. Then the user may make 6 melee attacks against that creature. At 11th level, the user may make 8 melee attacks against the creature instead of 6. At 15th level, if the flail hits the creature after the axe, the creature automatically falls prone and doesn't make a saving throw.

Moon Breathing:

Moon breathing was developed by Michikatsu Tsugikuni, brother to Yoriichi Tsugikuni, ancestor of Muichiro, and now known as the right hand man of Muzan Kibutsuji, Kokushibo. Kokushibo was once a demon slayer himself but joined Muzan to extend his life and gain power. He has never taught his form to another person and has had time to develop and cultivate it for hundreds of years. It has a minimum of 16 forms, but only 11 are known. Kokushibo's moon breathing technique would be very difficult in theory to learn as a human, due to the fact that he requires his blood demon art to control some of the forms and uses a unique katana made of his own flesh and blood. If a person becomes a user of the moon breathing technique, they gain a darkvision of 60 ft. and if they already have darkvision, it increases by 30 ft.

At 12th level, the damage increases to 4d8 damage instead of 4d6.

Fifth Form: Moon Spirit Calamitous Eddy (5 BP). The user creates multiple slashes to surround them. This move does not require the sword to be drawn but instead needs the use of a blood demon art.

Unfortunately for the Demon Slayer Corps, he lived 500 ft. ago and since has passed away. Tanjiro Kamado is one of the few people who can use this breathing style, the only others known to be able to use this style are the fathers of the Kamado family. This style is very powerful, and is considered the strongest style for a good reason. Yoriichi Tsugikuni made 12 forms, but made a 13th in a battle against Muzan using all 12 forms in quick succession to pierce and destroy Muzan's 7 hearts and 5 brains.

While you are wearing armor, you gain a +1 bonus to AC.

Dueling

When you are wielding a melee weapon in one hand and no other weapons, you gain a +2 bonus to damage rolls with that weapon.

Great Weapon Fighting

When you roll a 1 or 2 on a damage die for an attack you make with a melee weapon that you are wielding with two hands, you can reroll the die and must use the new roll, even if the new roll is a 1 or a 2. The weapon must have the two-handed or versatile property for you to gain this benefit.

Protection

When a creature you can see attacks a target other than you that is within 5 feet of you, you can use your reaction to impose disadvantage on the attack roll. You must be wielding a shield.

Two-Weapon Fighting

When you engage in two-weapon fighting, you can add your ability modifier to the damage of the second attack.

Demon Slayer Marks

While in the height of battle, you may activate demon slayer marks. Demon slayer marks look like birthmarks and look different depending on which person they appear on. You may choose to activate a demon slayer mark whenever you are below 25% of your hitpoints rounded down. Until the battle ends, you gain a +6 to dexterity and constitution while also gaining advantage on dexterity and constitution saving throws. Melee attacks you make deal an extra 1d8 force damage. However, activating the marks takes its toll. Anyone who uses a demon slayer mark, even if it's only once, dies before reaching the age of 25. Nothing can stop this or slow it. You cannot be brought back to life after you die due to the mark. The only person ever recorded to live past 25 was Yoriichi Tsugikuni, the man who invented breathing styles, although that is mainly due to the fact that he was born with the mark.

The Transparent World

At 18th level, you gain the ability to perceive organs, muscles, and blood vessels in others bodies. Almost all people who can do this have activated their demon slayer mark. When in combat with an enemy, you may choose to activate transparent world as a bonus action targeting a specific enemy. Until combat is over or that enemy dies, you gain a +3 to AC against attacks from that enemy and gain advantage on attacks against that enemy. Critical hits against the enemy deal triple damage and occur on rolls of 18 or higher. You may use the transparent world once per short rest.
