There is an incomplete character skills guide athttp://www.suikosource.com/kornholio/stskills.php
Still missing some characters, and some stuff for characters on there. Lazlo, Snowe, and Lalacle are among these (have never recruited them). If anybody has anybody of the missing information, post here
the link is to a blank page. I have had the BradyGames guide (for years). The skills are listed with each character in alphabetical order. Also listed are the Goodwill Partners. Lalacle is not in the guide but she'll have the same skill set as Karl as they're both the same type of fighters (hand combat).
Technically, any character can get to S mastery with any skill from their available skill set. The difference comes with how much skill points you need to use to increase the skill mastery (this is like a measure of the character's potential with the specific skill). Example, with Jeane you'll probably need to use around 3000 skill points to go from C mastery to S mastery with the Lightning Magic Skill, but with Maxine you'll probably need to use like 8000 skill points for the same thing.
I'll cover Lazlo and Snowe.
