Can someone fill me in on this `Kits` thing? I don't understand it at all. Is it like, you get a certain XP and you get access to these special `paths` to channel your Xp down, or are they, like, just mods for the main character?

What do you think I made my excellent Sorcerer's Guide to Kits for?? Read it from start to end and you'll know just about everything there is to know about them.

Read all about them here: http://www.sorcerers.net/Games/BG2/kitsguide.htm ;)
