It was over the duration of the 2 weeks or whatever that the dungeon was available for, so I didn't refresh to do it. Still a total waste though, especially considering I'm not terribly likely to actually uses the Leviathan. It was just the one I didn't have, so I wanted it just in case I ever wanted to make a mono-water row enhancement team with, say, my Lakshmi.
