Strategy Tips and Team Building
General Strategy
This entire fight revolves around priority control. In Phase 1, you can reduce the boss's priority unlike in Phase 2, so you need to abuse it as much as possible.
In Phase 2, however, the boss is immune to priority reduction, so you will need to make your characters as fast as possible.
Everything will depend on Skill Chains and CP generation, so equip your Sage and Rogue charms (don't forget your critical hit chance for Rogue).
In both phases, you want at least 1 healer for the thanks to the buff.
Quick tip : if you have モナド エヴァ at 6 stars in your second team you can stack up CP in phase 1. Swap to Team 2 when you're close to finishing phase 1 and trigger phase 2. Monad Eva will instantly the boss allowing you to keep the CP you built during phase 1.
Note : This video showcases an SSS Extreme clear. The same strategy can be applied to lower difficulties, but certain boss mechanics may be weakened or disabled. As the score is not unlimited before Extreme League, this requires less focus on building chain points in phase 1, you can use them freely.
