I'm thinking that he's going to be fairly stealthy, putting some points into knowledge: dungeoneering, going to try to make him great with animals and, if the GM will let me, let him ride his animal companion (given that he's a halfling and I'm spending the points on ride). The idea is that he'll be the guy you want to hire to take you in to a dungeon to scout out the way before you, offer suggestions on trouble spots, etc.
Thoughts and ideas?
