[The Witcher 3] What could Geralt have gotten if he had invoked the Law of Surprise when Gaunter O'Dimm asked him what reward he wanted?

Something that Gaunter had obtained without his own knowing, what could that be?

Well it would be a surprise wouldn't it.

That said, no one is even fully sure WHAT Gaunter O'Dimm even is. The form we see is only what we are capable of as humans. 

What or who ever he is, what ever could be a surprise waiting at home for him, could be something beyond comprehension that could warp the boundaries of space and time and reality itself.
