Path of the Chained

Some barbarians choose not to strike their enemy's body but directly at what times them to reality. Slashing the body isn't enough instead they seek to cut the very cord that tethers them to live, and their willing to risk their own fragile cord in order to do it. 

The Chained owe their existence to to powerful wizards who taught their ancestors the ways of asternal projection. As the generations passed fewer and fewer Chained could complete the projection. The art then evolved into quick dives into the astral sea in order to Chain another to themselves through their rage. 

Ethereal Shackles

When you choose this path at 3rd level, you gain the ability to bind yourself and another creature by your astral cords.

While you are raging you can use a bonus action to reach through the Astral plane and attempt to attach your astral cord to another creatures within 30 feet of you. The creature must make a wisdom saving through or be shackled to you until your rage ends or if the target moves out of range. The chain that connects you can not be seen in the material plane but can be faintly seen in the ethereal plane. A creature that can see the chain can use an action to sever the shackle. 

While shackled any damage you take is also dealt to your shackled target as the damage type that was dealt to you.
