Feat: Unstoppable Juggernaut
You have become a brutal, unstoppable force of nature, able to shrug off mortal wounds with ease. You gain resistance equal to 3 + your Constitution modifier to all damage, and your resistance from raging increases to 8 + your Constitution modifier.
In addition, if you are reduced to 0 Hit Points while raging, you can end your rage as a reaction to stay at 1 Hit Point. If you do, you become Wounded 2 (or increase your wounded condition by 2 if you are already wounded).
