There’s already a price being paid to discover the characters in The Big One. I don’t think the length needs to be obscured behind further costs.

If we think it’s too easy to use Churn the Mind to discover The Big One, let’s adjust the Madness cost or maybe the minimum length of The Big One instead.

part of it probably depends on if Darknight keeps making the big one an actual fish

there are only so many fishes of a certain length that I feel its a bit too narrow of a playing field.

That’s a fair problem. I think the best way to address it might be to go after the way that The Big One is actually created, or maybe the Fish Function itself. I have an idea, so let me take some time to write it up and see if we can have an alternative to burying every game step behind multiple cost walls.
