[@Nosuchthing] NPC's powers and their weaknesses would be really helpful for me to come up with a sensible weakness for a character of lower power. I am not arguing with the fact that characters might and should be outclassed - there is always a bigger fish and the PC's are not gods after all - but it'd make sense for the NPC's to work by the same rules as PC's even if they are on a whole different level, no?
