To those missing days on their ring.

I'm not sure if this works or not, but some guy in GFaqs is currently trying it.

If you upgraded your ring today, you got it to the next level and it becomes tradable. What if you trade it to another of your characters, one that hasn't done any ring upgrades today and try to upgrade it?

If it works, it might be a sweet way to recover some lost days on the ring. Sadly, I can't try it myself because I didn't lost any day, but it doesn't hurt to try (or at least wait to see if works for the guy doing it).

I could try this because my end ring is level 16.

I doubt it would work though.

This does not work, someone else confirmed it.

Confirmed already? It was too good to be true, then. :/
