I'm getting tempted to go for Level 9 instead of settling for 7.

3,000 masks is expensive, but with so many days left still to grind, I fear I'll regret leaving the criminals tasks on the table. It's such a waste to have them earn worthless corn.

I'm starting to change my mind. I just don't want any characters earning corn I'll never use, so I'll probably go to level 8. Don't think it'll make any real difference, and I see little reason to go to 9 since there are so few saints that don't already have tasks earning theatre masks. However, I just don't want any more corn!
