I've got a major breeding project going that requires studding out to other kings to get a specific marking from a few. This is really frustrating with the lionesses I have who already have a lot of what I need, and just need those two marks from one king each, purely because the kings who have those marks have 10 full slots. Not that I begrudge them that, just makes it hard to get the marks I already have and worked hard for to pass!

So I'm suggesting an item that would work opposite of how an ochre gnawrock would! Instead of forcing, say, slot 3 of the king, to pass, it would force it to NOT pass. This would not promise the lioness will pass her slot 3 mark of course, but it would give her a better chance!

Some differences it should have from gnawrocks:
No limit to how many can be used per lion/ess. It can't be used to force a 10 slot rosette or anything game breaking like that, so such a restriction shouldn't be necessary
Cheaper and/or more available! Perhaps you could purchase it in the monkey business, gorilla enclave, and/or oasis; or it could be a common event item, perhaps every 2-3 months it pops up in event shops for a low price!

Very open to suggestions/critique, let me know how I can improve this!
