Awesome. Thanks!

I'm going to go for broke then...

Natural herbs. Dio's FAQ says that, among other things, they make your COW do its special moves more often.

Does having more natural herb sets when you call a COW make it more likely to get a higher-level one?

Does having more natural herb sets make your COW hit harder in melee, or is that offensive? Or is COW melee damage not affected by herbs at all?
