Hello
I have a player who has a backstory that involves watching his family be killed causing him to fly into feats of rage. Now I know I could just ask him to take a level of Barbarian but really the background continues with him being sold into slavery and becoming a Gladiator. My question, is there a fighter archetype out there that Rages but is not involved with the Barbarian class?
Thanks
There is none. I mean, you could just flavor his fighting style as a rage. For example, the story of the iconic Ranger is that he flies into a rage and kills a whole camp of giants. He doesn't really fly into a Barbarian Rage, but that's still the flavor.
It'd be easiest to just make a quick and dirty Barbarian archetype for him.
Replace Trap Sense with the Fame ability. Give him the new class skills, and give him Performance Weapon Mastery at 1st level, and maybe that bit about armor.
From what I recall, it's not an overpowered combat style, so you won't have to worry about it being overpowered to just give the barbarian those.
