Focus on Arahabaki

Arahabaki will Call Allies to help him in battle. It would be best to ignore these enemies and focus on Arahabaki.

Hit Him with the Four Elements

Arahabaki blocks Physical so don't think of attacking him. Good thing Arahabaki is weak to Fire, Ice, Electric, and Force so taking advantage of his weakness will be easy.

Bring MP Restorative Items

This will be an MP-intensive fight. Furthermore, Arahabaki uses Spirit Drain, which steals MP from you. Keeping a good pool of MP will be crucial to winning this fight.
