And they're always the same class? I forget what they were, but could you spoiler their classes for me? I'd like my group to have variety and wouldn't want to double up on classes.
These companions are pretty much mandatory, correct? Otherwise the game is too hard?
To clarify, there are companions and there are henchmen. Companions are the same as henchmen except they're also written into the story. They have a lot of unique dialogue while henchmen have almost none.
There are currently only two companions in the game, a fighter and a mage. When you find them, they'll already be at level ~3 so they've already spent a bunch of their skill points but I believe you can still fully customize them as they level up.
