Also, make sure you hire pawns from the Rift. Not only is it fun to have a party of 4, when you release that pawn its owner will get an amount of RCs based on the xp the pawn earned with you, and the pawn will also increase its knowledge based on what it sees/experiences with you. So you're doing someone, somewhere, a favour.
For best effect there's an "active player pawns" thread on the Steam forum, where you can post your pawn's name/vocation/screenshot. People actively hire these pawns instead of random ones, which means the community feeds itself with those RCs. And once you get serious with BBI, you'll be glad you have these.
Just a word of caution: only ever hire level-appropriate (or underleveled if it's to help the owner) pawns. Overleveled pawns will ruin a lot of the fun. It's about *you* powering up and wrecking stuff, not someone else's pawn doing it.
