You don't like Jan? Well, IMO you're missing a lot. With his special equipment, he's both a good mage and an excellent thief. Jansen AdventureWear is the only real armor any mage can wear (it's not great, but better than what most mages get), and his gloves give a good lock picking / pocket picking bonus. His spectroscope also makes him a good trap detector, and the detect invisibility ability really rocks as it can reveal any invisible creature with a casting time of 1. Also he's a gnome, the only race able to combine a specialist mage and a multiclass.
Not to mention Jan's humor, which is a great balancer to the too common "For honor and glory!" attitude. Especially because Jan also dislikes such attitude, and you will have extremely fun conversations if you have Anomen in your party, altough he will jest with just about any NPC in the game.
Size doesn't matter. I gave Jan the Equalizer and a girdle hill giant strength, which made him a decent fighter as well.
Myself, I'd be ready to start a Jan Jansen fan club. Anyone else..?
