How many tokens does she want to use to charge the lock? Rules that somebody has probably explained to Opalyn at some point:
- You can't cumulate lock strengths; if you want to charge the lock with more tokens than before, you need to pay over the whole greater fee later.
- Somebody else, if they try to get in, has to guess how many tokens to try to use for an unlock. They spend all of those tokens, win or lose, and it cancels out her lock if they spent more.
