東方玄夢妖譚 ~ The Nightmare of Rebellion - 猪塚萩乃 参上!
She is weak against Water and Pierce (though I'm positive that she is susceptible on Rumia's Moonlight Ray).
Just because I'm overleveled doesn't mean I can breeze this boss like a piece of cake. She is one tough bitch! I did my best to hit her with Water attacks (Chasers were crucial) but I was almost ran out of POW and decided to play safe, finishing the fight normally.
Consider yourself lucky if she uses to focus her attack (in preparion to use her LW in the next turn) and either Yukari or Mamizou's LW kick in. Double lucky if both are activated.
There was a secondary Last Word Saya had this during the battle called "始まりの祝詞" which it can revive both the user and Main Doppel! Everyone can learn a secondary LW but it's by chance like learning a new weapon skill, making this a complete pain in the ass or just let it through.
One seal down, two to go! Keep it up, girls!
