Do prestige classes work with the multiclass XP penalty as well?
And ah, humans and half-elves have no class that doesn't suffer under the XP penalty right? THat's at least how I understand it.
yeah, but the XP penalty is only negated if the lowest class is the favored class right? That mean's that humans always pay the penalty when they multiclass.
