Beaten the game quite a few times (well quest lines at least) and i just want to power level a character for fun. So. Does anyone know where a higher leveled archer who can teach you and also be your companion so I'm not wasting thousands of gold? Please and thanks
(higher than faendal)

You don't "beat" Skyrim.

Anyways, there's Faendal in Riverwood and Aela in Whiterun.

Oxymoron

Aela (Expert).

Niruin (Master) Not sure he can be a companion though.
