Let's Play Genius of Sappheiros (Weekend) Part 26
It's that time again! Pair of bosses yet again!
Momiji/Cirno:
So Momiji is back and is more in line to a boss's power level now. Both her and Cirno have about 12k hp. Individually, these bosses are nothing special. But together, they are deadly. On the first turn, both of them will charge up and immediately use their strongest moves. Cirno's Perfect Freeze does ok ice damage while also Freezing your entire party. Momiji's special attack has ridiculously low hit rate but does enough damage to kill anyone in your part. While frozen, you cannot dodge so if the combo hits it is game over.
There are a few ways to stop this. Reimu's barrier can prevent Quick effects for one turn. But, I usually just pick one of them and kill her before they get a chance to do their combo. Cirno is vulnerable to Fire and is a Magician type while Momiji is vulnerable to Earth and is a Warrior type. Use Patchouli's Elemental Field manipulation moves to boost their weakness and use Byakuren to elemental weapon Sakuya. With that two handed sword and improved time stop, I did about 10k damage to Cirno before they even got an action. I could have repeated the process if I wanted but once one of them are down, the combo no longer works. Then you can kill the other freely.
