Path of the Enhancer

Enhancers are martial fighters who are capable of pooling their spirit to specific portions of their bodies or items they are holding, reinforcing them with a shroud of life energy. This can be used on any item; a rock and a bullet are more or less the same to an enhancer in terms of quality.

Enhancement

Starting when you choose this path at 3rd level, your rage allows you to flow your spirit into objects, reinforcing them to unbelievable heights. During your rage, you may flow this energy into any improvised weapon you're holding, whenever it's a blade of grass, a rock, a strand of hair or a sword. While improved, it gains the following benefits:

• It gains a thrown distance of 20/60 ft 
• It gains the magical properties of one weapon you are attuned to that is being worn by you (charges expended are expended from the weapon).
• It deal an additional amount of damage equal to your barbarian level

 

Ko Focus

Beginning at 6th level you learn to focus the spiritual energy of your body to spirt in response to hostility and your own intention, allowing you to move and react faster than normal. Once per turn, you no longer require a item interaction to pick up an improvised weapon. In addition, you have learned to harden specific parts of your body against attacks you can see coming; When you would be hit by an attack you can see, you can use your reaction to add your proficiency bonus to your armor class against that attack, and all attacks of the same name until the beginning of your next turn, up to a number of times equal to your proficiency bonus.

Explosive Ren

Beginning at 10th level, you learn to enhance things other than just your muscle and objects; you may also enhance your organs to make them extra effective and durable. As an action, you may swap which organ you are enhancing:

• Heart: Your bloodflow is increased, allowing you to keep conscious when you'd normally be knocked out. When you would fall unconscious, you instead do not fall until the end of your next turn (things like death saving throws are calculated as normal).
• Voice: You can use your voice as an improvised weapon, dealing thunder damage. Your voice can be heard from miles away, as long as it is not significantly obstructed, but otherwise can deal damage from 120ft away.
• Eyes: You gain truesight up to double your barbarian level.
• Brain: You can add your strength modifier to intelligence checks, and half the modifier to intelligence saving throws.
• Skin: You have resistance against damage from ranged attacks. 

Crushing Blows

Starting at 14th level, you face the pinnacle of your evolution, allowing you to flow spirit into anything you can touch. Your improvised weapons do an additional 1d12 damage. In addition, when you hit a critical hit with an improvised weapon, pick a limb. You inflict the creature hit with Crushed, cracking bone, and disabling that limb for a minute. While crushed, a creature's speed is halved if a leg is disabled, and if an arm is disabled, they cannot use items, weapons or unarmed/natural attacks with that limb. The arm ability can also be used on anything that has an unarmed or natural weapon attack, such as a tentacle or maw.
