Armament Haki (Busoshoku Haki)

This type of haki allows the user to create an armor-like defense with their bodies. This technique comes in handy when there is a need to skip past the devil-fruit defenses, especially Logia Intangibility. This was seen in the battle between Rayleigh and Kizaru. Armament haki has basic forms like observation haki, and it can be used in many ways for both offense and defense purposes.

Hardening Level 3

Hardening is the first and most common form of armament haki. The user can harden certain parts of their body or even completely coat their body with armament haki. The hardened parts highly boost the physical attacks and also act as a tank-like defense, which reduces incoming damage. The user can coat certain body parts with this haki. Another way to use this technique is to coat the body completely with armament haki. However, it should be noted that the more the body is coated, the faster the haki gets depleted.

AKA While your armament haki is active you gain resistance to nonmagical weapon damage for 4 rounds of combat three times day(at level 10 it lasts for 6 rounds, at level 15 you go up to 5 charges and at level 18 you gain 7 charges) you can activate it as a bonus action it doesn’t have the same restrictions as raging. It will last the full amount regardless if you attack or not same if you don't get hit.

Imbuement Level 3

Another great technique that comes with armament haki is that it can be imbued into any weapon such as swords, arrows, and more to increase the potency of their attack. Like physical attacks getting boosted by hardening, imbuement allows the user to use their weapons to create devastating and powerful attacks.

AKA You can Infuse some of your own haki to your weapon shortening the amount of rounds your haki will last(when you activate you haki it takes 1 of your charges you can add imbuement for one more of your charges) but gain one d4(one d6 at level 7 and d8 at level 10) for every attack(ranged or melee not spell ) you make. Your attacks are also considered magical for the purpose of overcoming resistances while your infusion is up.

Emission (Ryuo) Level 7

This advanced emission technique for Armament haki is called Ryuo by Hyogoro in Wano. This gives the user the ability to detach the haki from his body and utilize it to unleash an attack similar to a shockwave. The ability to attack enemies without touching them makes this move incredibly effective.

AKA  while your haki is active you gain a reach of 10 feet with most(ask your dm) unarmed strikes or melee attacks and weapons

Internal Destruction (Advanced Ryuo) Level 10

This is a more advanced type of armament haki that allows the user to emit haki (Ryuo) towards an opponent’s body, let it flow through their body, and destroy them from the inside without touching them.

AKA with your emission(while armament haki is active) now the person you strike will have to make a strength saving throw(dc is 8+ your strength or dex modifier + proficiency bonus) or be knocked prone and sent back 10 feet if saved it still moves back 5 feet but that is all. Your infusion can be added on to it. this is for melee attacks and unarmed strikes this cannot be used with ranged weapons or spells. You can only do this once per round of combat

Advanced Hardening Level 15

As a reaction you can try to push your self to your limits and protect your self and one other person in a 10 foot radius around you

To activate it will cost you a armament charge. While this protection is on you gain resistance to all weapon and ranged damage(magical and nonmagical) and so does this ally. If you do this and you haki was already active after when your turn comes back around again is turns off and you wont be able to activated it for a round. But if you do it while your haki was not already active or you were out of charges once you turn comes back around you are too exhausted and you skip your turn and gain three levels of exhaustion. You SHOULDNT do it again. 

Worry Less Level 18

You have trained your body to now activate your armament haki as a reaction and you can choose one type of magical damage that your haki protects you from while it is active
