Wow, and that's before Intangir, right? Have you faced him before? That Behemoth is just mean! You touch him when he's ******** and he will pound you into dust, and the Rinoa trick doesn't work because she will usually counter his attacks which trigger the retaliation.
I've been using all my nrg on the healing cryst caves. I know it sounds odd, but between the enhancements for Ayaka and OK (yes, OK) I actually ran out of healing crysts so I needed to bring up my stockpile.
The beach exploration is pretty good too with all the megacrysts, so now that the caves are done I think that's where I'll be using my nrg
.... except now they tell us there will be a UoC KM event coming up. Hopefully it will be a raid?
Also, did you see part 4 of the 7* banner summon? Part 3 has Ayaka but no one else I've thought about. I have Tidus & Emperor but I don't know if they are worth it.
BUT Part 4 has TT and OK! I might really have to pull on that one.
How about you? Did you get your 7* Aranea?
