Path of the Twinned Soul

Those who take the path of the barbarian are able to channel their rage through their twin. They are often born together as physical twins and are shown from an early age to have a strong link to each other, but it has been recorded for people who are not biological related to be a linked soul through the process of rituals. In the battle field they work together to protect each other and face any foe who challenges them.

Twin-tuition

 

You and your twin are able to ruthlessly take down foes in perfect harmony. While you are raging, if you and your twin are both within 5ft of an enemy and neither of you are incapacitated; you have advantage on attack rolls against those targets.

Connected through rage

Starting when you choose this path at 3rd level, the link between your twin becomes ever present when you enter your rage. While raging, if your twin is hit with an attack you can use your reaction to channel your link and swap places with them. If you do so you instead take the damage they would have took and as a part of this reaction can make one melee attack against the target if they are within 5ft. You can do this a number of times equal to your constitution modifier per rage.

Linked in Soul, Body, and Mind

At 10th level, you gain the ability to consult with your ancestral spirits. When you do so, you cast the warding bond or telepathic bond spell, without using a spell slot or material components. When casting these spells you can only target your twin unless your twin is dead. Constitution is your spellcasting ability for these spells.

After you cast either spell in this way, you can’t use this feature again until you finish a short or long rest.

Vengeful Ancestors

At 14th level, your bond becomes strong enough to bring your twin back from the brink of death. While raging if your twin drops to 0 hp you can use your reaction to heal them equal to half your maximum hp. You can only do this once per long rest and after your rage ends you take a point of exhaustion.
