Guard Stan:
Ah, the Blood Basilisk! Haven't given one of them out in... ooh... hours. Okay, I'll give you one Blood Basilisk for five Blood Werewolves and five Blood Drevanuls. Or you can try your luck in a game of chance?
"I'll just take the standard rate, thanks." "Let's play." [Guess correctly in two tries - 3 blood werewolves] "Let's play." [Guess correctly in three tries - 7 blood werewolves] "Let's play." [Guess correctly in four tries - 9 blood werewolves] "How does your game work?"
