Shin Megami Tensei V - Boss Shiva Hard Mode (Yuzu)

This was super easy for the so called "Super Boss" of the main game. I however do fear the Demi-Fiend. Still need some preparation to fight him.
Regardless, Amon and Cleopatra are the huge MVP's in this fight, an AOE Piercing Severe Attack (With High and Normal Pleroma) as well as a 1 turn -2 on ATK + DEF is huge.
Critical Zealot is also pretty good, I recommend using it as well as the pleromas on most end-game demons. Other than that, if things go south always have Enduring Soul in you party, you can farm this from Chimaera (Level Up Savescum).
