In this video we go back to the 3* Asura fight and do an updated clear with 2B. Here's the turn chart, but you have to adapt it based on who gets berserked: i.imgur.com/tT7eKKN.png
This is a rather easy one, especially with Paladin Sylvie. Using the Raise-Reraise strategy, P. Sylvie can both raise and reraise in one action with her normal attack. So you just need a magic cover tank with auto-cover (Shoreline Fina & Daisy for example) and 100% all element resist. And then it's just patience once your favorite element is debuffed. I didn't even use anything else besides 2B's base form, not even her shifted LB, and both 2B even without proper killers around the board did around 30% to 40% damage with each good burst.
Returner here. Heard of this fight. Went in Aggressive, smoked first form with 2B and Richt and Sorc Squall leader, plus P Sylvie. She returns and got her vengeance hahahah no easy otk for this!
