I haven't had a chance to try this yet, but it looks interesting. A couple of nitpicks after reading your PDFs:
- The Spellshaper kit entry mentions that at level 45, the duration of the Weaveshear ability increases to 15 rounds. I must mention that BGII: ToB can't handle levels past 40 to my knowledge. (Hey, if you found some way to make it work, I'd be interested in seeing it.)
I have this old level 50 mod from TeamBG-days:
http://home.tiscali.de/jo.ge/bg/dl\BG2_lvl50.exeI always have it installed, but I don't think I ever had a char with level 40+
- The "Ambidextrousity" ability name isn't a word. I believe the word you're looking for is ambidexterity - that is, "to have dexterity with both" (in reference to hands).
Hm... well, I'm no native english speaker, but as I understand it, ambidextrousity is a synonym for ambidexterity, maybe a bit more old-fashioned and maybe used because it rhymes with "virtuousity"
The word is used in some computer games (Jagged Alliance 2, the old Exile games, Dune Mud) for chars that are skilled with both hands, and I read it in real-life when someone described the skills of guitar-players like yngwie malmsteen that play the guitar using both hands.
Also,
dict.cc gives me 3 different translations for ambidextrous: "two handed", "sly/sneaky/scheming/duplicitous" and "bisexual"
