[v2.22]
For this fight, I usually use a spreadsheet to keep track of cooldowns and the state of my team, like this: ( https://i.imgur.com/8YJmDKz.png )
note: on this patch (as well as in v2.23), order of actions is random. In particular, on the last turn I wanted disruptive wave to be the first action, but it went second. However, Dargoth's patch fixes this issue.
The damage setup I used:
1. divine destiny (+ aqua pentagon)
2. maid boost + dullahan rondo + electromagnetic armor
3. electromagnetic armor + division + divine destiny + spellblade fire + 初心 (basic attack booster)
4. transform + focused mind + inner focused mind + ex tentacle up + electromagnetic armor + defend (+ offense song, hero song, daisy bell)
5. power charge + focused spirit + full power + flame dance fist + salamander + electromagnetic armor (+ encouraging dance)
6. disruptive wave + attack x 3 (+ pirate king song)
