Hiya!
And just to elaborate on what @
Sacrosanct said...
A character in D&D is a
character...not just a set of stats and abilities. I played a warrior-general type character. Massive strength, decent con, very intelligent and fairly wise. He was always thinking tactically, planning battles he could and utilizing the other PC's cababilities. He would wade into battle with his two-handed sword to help bolster his side and kick some ass! He had OK hp's, and his AC wasn't horrible, and he took a lot of damage during battle...but damn it all if he wasn't heroic and inspirational!
Oh, did I mention he was a wizard?

The point is that if novels/stories had been written about him, he would have been a pretty serious badass. He used his arcane training and knowledge to help gain an advantage or execute some battle plan. He was a "battle wizard", I guess. Even up into the mid-teens, he was often toe-to-toe with giants, dragons and demons. It just goes to prove that just because D&D doesn't have some specific 'ability' or 'class' that perfectly represents (in game mechanical terms) some character concept, that that character concept isn't able to be played. I didn't have to "fudge" the rules to make his concept work...I just had to play him as his concept and let the dice fall where they may (and the story play out however it did).
Conan in 5e? Same thing. I'd probably stat him as a Fighter (Champion), with the Criminal background. Then just play him as...well, Conan. If we were using Feats, I'd give him something like Skilled so he can pick up some skills that fit his concept. Maybe that one that gives you more HP's as well.
Anyway, IME how a player actually
plays the character makes FAR more of a difference in how the character is perceived than what stats/skills/feats/whatever is listed on his sheet.
