New class starts with a class-exclusive spell that charms Zuul. Pretty useful, if not totally reliable. Also is great at the "other Psi skills" that the Psion and Seeker lack - War Mind especially. But sadly, no Telekenesis on this guy, so you really need to slog through some skill point investment if you ever want to TK fist anything. He gets a lot of them, though, and starts with pretty good utility skills, so he actually has the option to eventually learn the TK Fist. It's just really painful trying to figure out how to deal with mecha before then... they'll blow up your Zuul Pup and then turn on you, and if you only have your starting Snub Pistol and Painbringer at the time, you'll have no choice but to take a few hits in the process, owwww.
I don't really know the best way to play this guy. High utility probably makes it profitable to avoid some fights and blow other ones up with your goodies.
I had bad luck with weapons. Luckily I got a crowbar to replace my melee weapon in time, but my Snub Pistol got stolen (oops), and I never found another ranged weapon except for a shotgun I threw out because I wasn't hoarding shells.
God, there are way too many ammo types in this game...
