Shin Megami Tensei V: Vengeance - Satan Hard (No DLC/NG+)

gg ez

Okay for real though, this was a pain in the ass to do. I don't even know if there is any other way to beat him on Hard specifically. The main issue is his Megido Ark skill which from my knowledge is a guaranteed ohko if you have 3 demons on the field, so either you fight the boss solo for minimum damage from Megido Ark or you make a situation where he doesn't get to use it at all. He only uses Megido Ark in his final press turn when he gets to act again, this is significant because if he were to lose press turns before for any reason it would never reach to him again to use Megido Ark. This is why we have Luminescent Mirage which makes Nahobino guaranteed to dodge the first attack he is hit with. Because of this, he loses 2 press turns and doesn't get to act again later. Although if you are hit with Figment Slash which Arahabaki and Ganesha love to use (and rarely miss????), it is guaranteed crit which offsets the turns he lost and can use Megido Ark. To prep for that scenario we have to have Enduring Soul on everyone and hope that he doesn't use it on the same demon whom he hit on turn 1. And since we are using Luminescent Mirage, the best move to go for is Paraselene Blur since it is the strongest DPS Nahobino has access to with the caveat that it can only be used if you evaded an attack the turn before. That's not an issue since we are guaranteed to evade one attack due to Luminescent Mirage. The idea is to then setup 6 acting turns to do massive burst damage with Paraselene Blur.

We need Beelzebub's trait to do double debuff using debilitate. Baal's trait gives you an extra full press turn when the opponent uses any debuffs, this is a massive wincon that can be helpful during the burst turn. Norn's and Dis's trait allows them to get withdrawn to stock on their turn without consuming any press turns. Although this didn't come into use in my run, but Mithras' trait allows him to give a free +1 buff to all stats once he is summoned.

The way you get the burst damage turn is either opponent uses debilitate which activates Baal's trait or Nahobino dodges twice (one is guaranteed, other is rng). I had to wait till he absorbs Kaiwan so he gets a Light weakness and then you see what's in the video. You can do this earlier as well if you get both of them at the same time giving you 7 turns to work with (here you would need to change Baal after using Omagatoki Charge to Mithras to get the buff to offset the debilitate) but I went with the more consistent strat.
