Ah, I know about the problem with the BioWare spellbook, I just don't mind. I never had complaints using metamagic with it, but I do with the new spellbook system, for 2 reasons: there are far more spells, making quickslotting annoying, and there is no organization, making numpad casting impossible.
Plus, and this part really has me excited, it's going to be so flexible now! I'll probably have a hard time moving back to prepared casters after being able to toggle metamagic at whim, and combine it as well!
Thanks for the info about the spell scripts. I didn't think of that. I completed the new metamagic system last night (except for the spells, I guess I'll need to look at those), but I won't actually have time to test it out until later on this evening. Cheers!
