"Yes, there's a bunch, historical wizards were really concerned with the fertility of their crops. --Why? You want to kiss someone in the rain?"

"Ah, si-mei, don't you know that I'm so beautiful that I summon rainstorms whenever I'm sad?"

"It's a very useful skill!"

"Anyway"-- he grabs her hand, bows over it, and kisses the back of it-- "my lady, your statistics await."
