Chances are, this might die off quick, seeing how so little commented on the previous topic, but I'll try again for the last time:
I was able to reach extra mode with all 4 characters a few months back, but difficult to move around and progress without proper equipment & help (more on help), but one thing I noticed that the accessories (or rings) dropped by bosses of said difficulty grant massive bonuses. So I was wondering, does anybody have a list of all the rings that can be found in Extra difficulty? I only found like 3 types so far, I wonder if there are more. I tried looking around in many sites, but to no avail.
