"I eagerly await your attempt."

Said with the smug confidence of someone who has an absolutely overpowered amount of spells at his disposal.

"My blood is in all honesty not going to do much. That's not where my power is stored. However; if you do manage it, I'll simply come back and telekinetically pull your bones out of your body." Not really a brag, just a statement. "You must be new here."
