As someone who doesn't have the mercenary pack, I was just curious in knowing a few things about it that weren't obvious to me from reading about it online.
I'm aware you can only make a level 20 character into a mercenary, but there's a few other (more obscure) things I'm curious about:
-Can you use mercenaries with characters who are not yet level 20?
-Is there an in-game cost to use them (ie. gold fee, etc.)?
-When you initially add one to your party, do they come with any skills in their skill bar (I'm aware they have access to all unlocked skills)
