Jayce gives him a strange look, confused. If he thinks there's something he can do, why not try, "well... ok?" He removed his shirt and attempted the spell again as instructed. A seal starts to glow on his back once again, clearly magic used for sealing something. With closer expection it seems to prevent mana to be converted into spells. It's simple in construction yet quite potent, clearly the work of a powerful mage. This new attempt Failed as Jayce expected it to, "so, any ideas? Is there anything you can do?"
