the all damage resistant Barbarian Multi-class.

[Xavier Forget]

I made a character sheet for a Barbarian/Warlock multi-classing. Going with the path of the Totem Warrior is the way to go, and a Warlock Fiend, or Great Old One. Go the path of the Bear to get damage resistance to everything but Psychic damage with a 3rd level Barbarian, then with Warlock go: Fiend or Great old one, at Level 10 for both. The Great Old One though has the better end of the deal with the Psychic resistance being resistant to Magical and silvered. Also the Psychic damage you take does damage to the one dealing the psychic damage. Only thing is it will take a long time to bring up your character to at least 13th level.

The UA mystic, with intellect fortress, can get psychic resistance at level 1. There's also a ring.

Any THP (Fiend, armor of agathys) is effectivly doubled with resistance. Just be aware that you can't concentrate while raging. Also, low-level bear barbarians only get that resistance for a few battles a day.
