Reconstructed

Being reconstructed may not have been the first choice of the Barbarians that undergo the process but it gives them unique advantages over those without modified bodies. Infusing their biology with parts of constructs to build a better being capable of less natural feats.

Reinforced Muscles

Your body is interwoven with parts of constructs to reinforce it and provide it with additional power

While raging if an effect triggered by you attacking causes you to take disadvantage on an attack you can spend your reaction to ignore that effect.

Additionally you make all grapple checks with advantage, even while you are not raging.

Rebuilt Skeleton

Your skeletal frame is coated in a layer of metal, making it even stronger and resistant to damage. 

While raging you take no damage from falling or having objects the same size or smaller falling onto you. Such objects can still cause you to become restrained.

You can also prepare for a fall while not raging to avoid taking damage from it as long as you can see where you will land.

Quickened Reactions

Your nerves are infused with magic normally reserved for commanding constructs. 

When you use the Dash or Dodge action you may move an additional 10ft. 

When you use your Danger Sense ability you can choose to pass the check instead. You have uses of this trait equal to your dex mod (minimum of 1). You regain all expended uses after a long rest.

Constructs Might

Your mind and body are further strengthened to give you greater survivability. 

While raging you gain resistance to Pyshchic and Necrotic damage. You also gain advantage on checks to resist being knocked prone. 

Additionally your danger sense ability also applies to Constitution saving throws.
