Lower cooldown on Eternity Ring?

[Yamimarik]

I cant remember but isnt the 1 for "friendship" limited like it only lasted 1 month or something?

The limit on it I do believe (I have it, and nv have used it lol.) is that it has to be with a new person (leaf on their name) on your friendlist. Correct me if I'm wrong though, but I don't think it just lasts for 1 month, just as long as your friend still has the new adventurer symbol on their name.
