Demi Fiend Hard Help

[MilkyTea21]

Hey guys, I know I just posted here recently, but I need some help and advice.

I have been trying to fight the Demi-Fiend and while I am able to deal with his physical moves thanks to fusing and essences, I'm simply not comfortably doing enough damage:damage received to him or his party.

My party are all level 99 with high element pleorama and additional boosters to increase damage.

If you do not want grind more demons and switch them out - just do the 2 turn strat described in this video

Otherwise you will need to bring a few additional demons to target his party weaknesses. As well as having your character acquire a few evasion moves from Tsukuyomi late-game essences will make this fight incredibly easier.
