You are one of the many humans adventuring through the Black Tower, hoping to reach the top. So far you are at the 15th floor, which is pretty good, or at least you assume so. As you're exploring the floor, you get a system message randomly, "The Tower Manager has issued you a new quest!"

Quest name: A Special Offer

Description: Give up something in return for a "reward."

Quest refusal penalty: Death!

You stare at the Quest for a couple moments, you've heard from others the Tower Manager usually isn't serious about just killing someone over a Quest, but... something just feels, different about this Quest.

What do you do?
