I wanted to ask a question. Your emulation of PnP class abilities, maneuvers, invocations works via feats. I see how it may be difficult to remove a feat, but it seems to be possible (when you lose a level or more, you lose the feats too). I think I could swap out old maneuvers when I played Swordsage in SoU. Now I played original NWN with Warblade, and couldn't do it. So is the problem with Warlock's invocations - you can't swap out the older ones.
Is it possible to implement this feature? If yes, is it easy enough for total newbie to do it? ^^
