Ki practitioners are capable of many miracles, from using this magical energy to heal grave wounds, to committing feats with their bodies that are impossible otherwise, but those who chose the path of darkness form techniques known as 'Forbidden Arts'. Due to their dangerous and powerful nature, these skills are usually kept secret and otherwise banned to outsiders from abusing them. One of the many 'Forbidden Arts' whose methods are based on a specific weapon and element, an ancient sword known as the 'Katana' and 'Air', wielders of this technique are renown to finish fights in a blink of an eye. With a blinding flash of steel as they brandish and immediately sheathe their blade, they strike with such force and swiftness that it appears as though the very air that produces from the motion becomes an extension of their weapon. Able to spill the blood of opponents at a distance, this is known as the 'Bladeless Sword' While needing to use the proper technique holds great importance, the other half of the technique comes from the user's control and understanding of 'Ki'. Those who choose this path train rigorously develop their skills in three different forms, creating a foundation through way of 'Ki', using it to forge a close bond with the element of 'Air', and then finally using this link as a foundation for their unique style with the 'Katana', blending them all into one graceful yet deadly Art-form channeled through the body through breathing techniques, infusing the oxygen with one's ki, creating a vortex of gale in one's self, empowering their mind and body.

Steel Tempest

At 3rd level, you must form a bond with a Katana, giving it a sacred name and performing a special ritual of meditation over the course of 1 hour, which can be done during a short rest. The weapon must be within your reach throughout the ritual, at the conclusion of which you touch the weapon and form the bond, muttering the name you have chosen. This weapon is now considered a monk weapon. After you have a bonded Katana, you may adopt the unique stance of 'Steel Tempest' whereby you assume a combat stance revolving around your weapon being sheathed for attacking and defending.

1. With this technique, being attacked while having your weapon sheathed will not trigger a disadvantage so long as you are not surprised. After being attacked, your weapon is now considered drawn.

2. Any attacks made by your weapon are coated with gale, doubling the range. Enemies entering this extended range will provoke a disadvantaged attack of opportunity

3. While your katana is sheathed, it is passively creating wind pressure within the sheath. In 5 turns, it builds into a usable force. Using an action move, you may re-position behind an opponent that is no further than 15 ft. from your position and attack once, doing 2d10 damage, increasing by 1d10 at levels 5, 8, 11, 17, and 20.

Gathering Storm

Starting at level 6, you have now overcome many perils and gathered much knowledge from your adventures. Your mind has grown keener from your experiences and is able to remain focused and concentrated regardless of the situation or danger. Also, from your daily practice in this art, you grow a stronger connection to the Wind and are now able to read any movements in the air around you in 45 ft. radius. Because of this, you are unable to be surprised and even without using sight, are able to distinguish the layout of your environment.

When you acquire this feature, 'Steel Tempest' gains extra effects. With your connection to the element of Air growing, as with your control over Ki, the wind around reacts to help protect you.

When wielding your bonded 'Katana' you gain + 2 bonus to your AC. In addition, the blade of your bonded Katana is covered by a concentrated wind-based ki layer, giving it a + 3 to each damage roll caused by the weapon and will considered magical for overcoming resistance.

When you make a melee attack  with your Monk Weapon or unarmed attack against a creature, you don't provoke opportunity attacks from that creature for the rest of the turn, whether you hit or not.

Second Wind

At level 11, your power over Ki and your link with Air reaches another notable point. All of the Air residing in your body causes you to weigh considerably less, giving you the trait of 'Guided by the Wind'.

Because of your gliding, wind-like movement, your steps no longer produce sound and gain advantage on any acrobatic or athletic check.

Your body passively creates and absorbs Air, eliminating your need to physically breathe.

Your are able to hold your breath for 4 times your monk level in minutes.

Beginning at 11th level, you can attack three times, instead of twice, whenever you take the Attack action on your turn.

 

Winds of Fury

At level 17, you are allowed to spend 4 ki points to cause your next attack to be infused with a powerful gust of wind and launch the target upwards into the air, stunning them for one turn.

This enhanced attack will deal twice your weapon damage. The height this sends them up is equal to 5 times your highest of your dexterity, wisdom, and strength modifiers. Rushing up after your target, you float in the air and unleash a barrage of strikes upon your helpless foe before sending them crashing down to the ground below.

Along with all of your hits with your standard attack action, you may spend any additional bonus actions or reactions to add one extra attack for each spent. At the end, you finish the combo with another wind-empowered attack and send the target downwards with a powerful sweeping current. This attack will deal twice your weapon damage at first and double falling damage. After using this ability, you cannot use it again until you finish a short or long rest.
