Could it be renamed to something like Adrenaline Rush, where he gets faster instead of stronger? Half-damage could be loosely played by heightened reflexes to shift away from the brunt of the attack instead of mentally powering through the wound.
Made me think of the Bladesingers. How about calling Mai'ngor's rage-like ability Blade Dance?
Just so you know, I don't intend to take any more Barbarian levels. Going forward, Mai'ngor is going Fighter all the way. That's the plan, anyway. Looking back, I think thematically it would've made more sense if I had started him as a Barbarian given his story. Anyway, here we are.
