User blog comment:Liquis/I Need Some Help With The Mech Gods/@comment-209.18.52.52-20150508135428

I easily beat water mecha with lvl 50 (B) 6* rosetta leader, lvl 50 (A) 6* Colt SBB, lvl 78 (A) 6* Shera, lvl 50 (A) 6* Rosetta, and a max level 7* SBB Feeva friend. I didn't even have a 5th member, I used about 4 high cures, 2 divine lights, 3 ares flutes, 2 fujins(to make it faster). Just make sure you heal and mitigate every turn and generate BB very fast. Bring units with more than 5k hp and 1.5k def and you're set. Hope this helps! Also only 1 mitigator is needed, if you can't generate BB safely, bring 2 mitigators
