[And Sanji can't promise him a shift wouldn't come with detrimental effects. He still remembers the time when one rendered him blind on the battlefield.]

Yeah, a Shift. Kinda hard for me to explain, so you might be better off asking someone else. [Still, he gives it a shot]

Here, let me give you an example. In this village we get Shifts a lot. Sometimes we'll start randomly teleporting, or we'll think something is true when it's not... like falling in love with someone you've never met before. Or swearing up and down you're a shitty scientist when before you were a seamstress.

It's always some type of abrupt change, and it can simple or complicated.
