I didn't choose the trigger. But it works best that way, so I've refined the spell to take advantage of the natural potency."

The flames of his third eye are still going as Strange continues to examine Ignatius, as if this will somehow give him a better idea of how best to help. There's a little pause before, Strange continues, not really sure about how to say this. "By the way, I think I'm fireproof now. One of the tests they ran on me involved your power with some...unexpected results."
