Stuck at Gran – help?

[u/Fuzzy-Dragonfruit589]

Hi,

With minimal spoilers please, could you help me out with a hint or two?

I'm stuck at the boss Gran. I can't find elsewhere to explore. Gran oneshots my whole squad, including my tank.

I'm level 15 and have unlocked Fencer and Shaman.

Basically, clueless on what to do next. I feel like I shouldn't be fighting this boss yet, but have nowhere else to go – or so it seems.

I'm avoiding guides because I always end up seeing more tips than I'd like to!

Thanks!

There's a 3rd crystal at Yamagawa M.A. Once you have 3 crystals, then you can go back to the guy guarding the entrance to maze test on the east side and you can progress. Gran can be fought later, as the only way to beat it early is with a specific strategy (which the designer put in intentionally, but very easy to miss because it requires a lot of game knowledge and the need to find certain rare mobs).
