Well, I don't consider either example to be an RP concept. I guess we have different ideas of what 'RP concept' means. You can absolutely achieve a valid "hero out of legend", or even "hero's sidekick", using standard array, IMO. AFAIC, descriptors do not usually equate directly to RP concept. YMMV.Based on some rolled stat characters I've seen - an RP concept that absolutely requires that no stat be lower than 16. Because your character is a hero out of legend, even at level 1. Purely for RP purposes, of course.![]()
Conversely, if you want to RP as the Legendary Hero's sidekick, you may want to have no stat higher than a 14 and most of them at 10 or below. Can't do that with the stat array either.
Regardless. No, you shouldn't, in good faith, being asking to play "omnipotent god", for example. Or other specific descriptors that exceed, or violate, the expected baselines the system assumes. Unless it is understood in advance. But then I'd have to ask why such a group is using standard array in the first place.
