Ok, I'm sort of a newbie, so I'm going to ask a newbie question. I looked around for a FAQ but didn't see one, so I hope you'll forgive if this is asked frequently. I understand the multi-class rules, but the prestige class rules have me confused. It says in the DMG that Prestige Classes obey the rules on multi-classing. Does this include experience penalties. For example, if I'm a human and go Cleric 3/Wizard 3/ Mystic Theurge 10, am I in the penalty zone for having that Prestige Class so far away from my base classes. What if I then add another prestige class so that I'm Cleric 3/ Wizard 3/ Mystic Theurge 10/ Spellsword 1 (or something)?
