Imply I'm the one who destroyed the City Olnmar

"That's funny," I tell him. "That's basically the same the people of Olnmar told me before I wrecked their beloved city"

After I say that, there's a long pause in which none of us says anything.

"You're bluffing," the mage says.

"I guess that leaves only one way to find out then." My heart hammers in my chest as I say this

The few seconds of silence that follow are longest I have ever felt but after the long pause the mage finally says "You're in luck Swift. I'm feeling merciful today. I'm going to be out of your hair once I finish poor old Garrick here.

"You do that and you'll regret it" I say without thought

"What!?! Are you kidding me? You're going to defend this excuse for a mage?"

"If I have to... Do I have to???"
