Okay, so here is the situation. I have a lvl 4 Rogue/lvl 3 Fighter/lvl 2 Shadowblade character, which is all fine and well. But I am curious if I can take my next level in Rogue or Fighter or if, having taken the Shadow Blade prestige class, I am locked into either leveling that class or taking another Prestige Class.
I haven't found anything that says I can't level the base classes, but I seem to remember a past DM telling me that I couldn't. So is that the case, or was that specific to that DM, and not really the case?
