Er - how often does Wish get cast except by Astral Pretenders? A top rank Astral mage is S4. Starshine Skullcap, ring of sorcery, ring of wizardry take that to S7. Replace the ring of sorcery with the Forbidden Light, S8. I guess you could always empower a mage from S4 to S5, and for nations other than Arco, R'lyeh, and Pythium, you have to empower up to S4 and then S5? (And then see your Empowered Wisher get killed by the Horrors the Forbidden Light brings.)
