All of his magic items were put up, so it was literally his own constitution and the mantle versus whatever the spells threw at him, as well as having to handle the strain of the mana screaming through him back to the Queen. She was going to get significantly more power than she had thrown at him for Sapphire, assuming he didn't fail to properly channel the mana, and ignite as the mana grounded itself through him. He simply couldn't back out now, he was fully committed and couldn't back out now, he couldn't even see Sapphire or knew if she had gotten clear. All he could do was keep turning the mana sink around him, and hope.
