I know that there is a mod that eliminates the unlockable charms from challenge shrine. But hear me out.
With the 1.2.0 update we have 74 charms if i am not mistaken. If you get good run with a lot of money you can get maybe 10??? but more often then not its less. So sometimes when you want to try some funny, exciting builds that rely on few specific charms, the odds of getting them are getting so small, it honestly feels like finding a needle in a stack of hay.
Maybe a fix could be an option to toggle unlockable in a challenge shrine. Maybe putting it behind a glass, so it looks like a display case in a museum, or something like that.
