shera is a thunder darvanshel that boosts attack instead of def with double the BC for SBB, so not a necessary upgrade, but good to have. Especially with content later that requires more squads.
arus... think i like rowgen better because he's easier to spark.
Belfura, not sure.
Yeah, the double BC for SBB isn't so hot, but hey, she still has 26 drop checks on her sbb which makes her much better at bc gen.
Regardless, I don't need her, and I got some okay stuff through that, although 5 Arus is funny. I might just keep 2 (an Anima and a Breaker, just for kicks), but that's it. I'll finish evolving all my Zelnites for my Zelnite troll team, though - I wonder how good it would be for FH since I'd be sparking like it's nobody's business.
In other news, I *finally* got Maxwell! I figured out what I was doing wrong, but I kinda cheesed it with dual Tridon.
Basically, I had
Leader Tridon with Medulla
Darvanshel with Dandelga + Sol Creator
Ulkina with Drevas
Rowgen with Batootha and Steeple Rose (LOL DAMAGE AMIRITE)
Zelnite with Legwand and Sol Creator
Friend Tridon with Ihsir's Guise and Dandelga (op!)
The big thing I was doing wrong is waiting to activate Tridon's mitigation until it was SBB, which was a huge mistake. It's always better to activate ASAP in this fight, even if it's not SBB, because you do it for the extra mitigation, even if there's a bit less in the shield. It makes a huge difference, really, and I finished the entire fight with nobody dying once. Once Maxwell died once, I killed her in 3 turns (Rowgen did all the work there, but with Batootha and Steeple Rose he does +100% spark damage, so it was taking a huge chunk out of her life).
She's now sphere frogged and I have 33 Burst Frogs. I don't know if I'll just try to level her BB manually to save them a bit (I'm building my crit squad now, and my Kuda is BB1 so he needs it too!)
It's now time to farm for Amanohabaken spheres! It'll take a bit more time than farming for Sol Creators, though, but I should be good. It's pretty easy to do.
As for a crit squad, I think going Maxwell + Kuda + Elza is good. I think I'll put Zelnite and Mariudeth in the squad, and I should be good to go - Kuda for ATK buff, Mariudeth for the crit buff (at 45% + amanohabaken I'll reach 60% crit, which is good), Elza for extra spark buff and Zelnite for all-around OP-ness, but I'm not 100% sure.
