Hmm.. Perhaps a better question would be, if Odium, Honor and Cultivation were on any other planet would their systems use such huge amounts of investiture.
I'm wanting to know what makes Roshar so special. Is it the planet or....?
Exactly. So why is it that the magic systems have such a disparity in Investiture consumed? ( consumed is I believe the correct word because I don't care about the available Investiture only Investiture used by the magic users ( we need a word for magic users. ).
