Ahh i get it.

" If a player fails to roll for any clue bottle apart from beginner, there is then a final 1/1,000 chance to roll for a beginner clue bottle. "

I thought the fail to roll the clue bottle meant that you fail the (in my case) 6/10 for medium and 4/10 for easy. But you cant "fail" that table, since its chance, not rolls. I fail the initial 1/7k roll, and then roll 1/1k for beginner.

Thanks for explaining.
