Path of the Outlander

There is something feral in each of us, something that rebels against society and seeks the freedom of the expanse.  Those who follow the Path of the Outlander live their lives free from the trappings of civilized society.  Outlanders live in small, often nomadic, cells that travel across wildspace.  They're rugged and tough, and often fight unarmed as they'd rather use what salvage on keeping their tribes on the move than making spears and axes.

Improved Unarmed Strikes

At 3rd level, your experience in combat has made you a deadly weapon. You can roll a number of d4  equal to your proficiency bonus in place of the normal damage of your unarmed strike.  Additionally, you add your proficiency bonus twice to your attack roll for unarmed strikes and your unarmed strikes benefit from your rage bonus.

Stubborn Resilience

Starting at 6th level, you've learned how to shrug off blows that would kill the common person.  As a reaction, you can expend a hit die and gain bonus hp equal to the roll, plus your constitution modifier.

Indomitable Might

Starting at 10th level, your fury has turned you into a juggernaut on the battlefield.  The damage from your unarmed strikes are treated as magical.  In addition, you are immune to psychic damage, and the charm, frightened, and sleep conditions while enraged.

Furious Blows

Starting at 14th level, you have become a weapon of legendary prowess.  Your rage bonus applies twice to your unarmed strikes, and your unarmed strikes are critical hits on rolls of 19.  If you are at half or less health, rounded up, your unarmed strikes are critical hits on rolls of 18.  If you are at 1 or less health, your unarmed strikes are critical hits on 17.
