I started a game with my PC as a fighter. I have picked up the companions who are a chanter, priest, fighter, ranger, and wizard.
I'm running into problems of being unable to open locks. I'd rather avoid wasting gold on custom characters if I can help it. I checked the wiki and there isn't a rogue companion.
I just reached Defiance Bay but I still have some quests at Gillded Vale.
Who is the best companion to train as a lock picker and trap dectector?
