Way of Hamon

Also known as Ripple, Hamon is inside of most people though they would never know. To control Hamon, the monks must have a proper breathing patter, regular bloodflow, and healthy life. These monks are able to infuse themselves and objects with their Hamon, which then will make themselves, or the objects, effective weapons in battle. Hamon is mostly used for protecting the body from aging much, protecting against undead creatures, and attack said undead creatures. 

Hamon Novice

When choosing this subclass at 3rd level, you start to control Hamon by using your ki and training. By spending 1 ki point, you may activate your Hamon for 1 minute or until knocked unconscious, breathing is cut off, or blood flow is cut off. While Hamon is active, your body is covered in yellow rays and sparks.

When Hamon is active, your unarmed strikes may deal Radiant, Lightning, Fire, or Piercing damage. If a critical failure is rolled, you must make a Con Save (DC 15) or lose control of your Hamon, ending its effects. When Hamon is active, you may use an action to infuse items with your Hamon. Infusing an item with your Hamon makes it do the damage you assign to it, but only for one attack. Items that may be infused include melee weapons, ammunition, and improvised weapons (Using the improvised weapon with Hamon would give your proficiency bonus.) The Hamon infused on ammunition will remain infused for an hour or until used in an attack, you are also able to infuse five pieces of ammunition at a time. 

Hamon Control

At 6th level, you are able to better control your Hamon.

You can spend 1 ki point to use your Hamon to give yourself a climbing speed (Including upside down) or the ability to walk on water equal to your base speed. When climbing, it only requires your feet, which allows you to still make attacks. This lasts for 10 minutes. 

Your attacks when Hamon is active, or infused into them, now ignore all resistances of Undead creatures.

You can spend 6 ki points to cast Control Water at 4th level, as if you knew it and had a spell slot for it.

Hermit Purple

At 11th level, your Hamon has become so advanced that you have the ability to summon a manifestation of your Hamon. This manifestation appears to you and other Hamon users or people that can see souls. This manifestation appears as purple vines covered in thorns. This manifestation shows up when your Hamon is activated or using one of its abilities.

You can spend 1 ki point to summon Hermit Purple, laced with Hamon, and cast Thorn Whip, "Hamon Lash" as if you knew it.

You can spend 1 ki point to summon Hermit Purple "Hermit Grapple" and swing or pull yourself 60ft (Like a grappling hook).

You can spend 1 ki point to summon Hermit Purple and cover your body "Hamon Armor", this lasts for 1 hour. While this is active, Undead creatures have disadvantage when attack you with melee weapons. When hit with a melee attack from an Undead creature, they must make a Con Save equal to your Ki Save DC or take 2d8 of a damage your Hamon can do. You also gain resistance to Necrotic damage.

You can spend 6 ki points to cast Scrying, "Hermit Vision" as if you had a 5th level spell slot for it.
