ill answer with a question.
Is there a reason to get the skill up? since you cant use it?
shrug. I never did use it as you cant do anything with it.
magic users ftw!
real answer. I think the shop was the only way I found, though I believe there are things one can do.
but again.. not sure. brigand was my least tested newest patch path.
wish I could help, prolly reply as brigand just to have some fun later
makes me wonder when the guide/artbook is coming out so we can see all this stuff in the booook!
oooo
