How to face Oni

In order to face Oni in battle, start the subquest: “Movin’ on Up”. From the Nagatacho Leyline Crossing, head to the northwest path to reach Oni. Reach the end and enter the west cave. Accept the subquest and talk to the four demons outside the cave. Report to Oni and he will go outside. Catch up to him and get ready to automatically battle Oni.

Oni Boss Setup

Here is a breakdown of the battle preparation against the boss:

Carry HP and MP recovery items

Before engaging the boss, bring HP and MP recovery items in case your party runs out of HP and MP during battle.

Max your Magatsuhi Gauge

In addition, make sure that your Magatsuhi gauge is already maxed. Having it maxed prior to battle is helpful in setting up your offense. Also, having a Miracle skill, Magatsuhi Wellspring, will provide your party HP and MP recovery at the start of your party’s turn.

Assign Nahobino Elec and Light skills

Make sure to import Electricity and Light skills if you can in order to exploit the weakness of the boss. Otherwise, you can rely on your ally demons to have those skills for you. To add, complement your offense with strong Physical skills like Aramasa.

Support and Passive skills can boost your damage if still have skill slots. Recovery skills are optional if your active party members do not have these skills. This is to sustain the party during battle.

Attach affinities to Nahobino that nullify Phys skills

With the Divine Amalgamation Miracle, Nahobino can implant skill potential from essences. Add to Nahobino affinities that can Reflect/Absorb/Void/Resist Physical skills.

Pick ally demons that can counter Phys skills

Bring party members can innately Reflect/Absorb/Void/Resist Physical skills if possible. If you can’t, make it a point that their weaknesses are covered during battle.

Add demons that can use Elec, Light, and Ailment skills

Similarly, add demons to your active party that can use Electricity, Light, and Ailment skills. If they don’t have access to those skills, utilize Essence Fusion to grab those skills from demon essences.

Oni Boss Strategies

Here is a breakdown of the battle strategies against the boss:

Pass action to support demons

If you start the battle with Nahobino and don’t have access to debuff/buff Support skills, make use of the Press Turn System and pass your turn to demon allies that can use debuff Support skills.

Land debuffs

Land debuffs on the boss while leaving some MP for recovery. Debuffs can be in the form of attack power decrease (Tarunda), defense power decrease (Rakunda), and hit/evasion power decrease (Sukunda). These debuffs can be accessed by Nahobino and any demons in your party.

Prioritize on landing Sukunda first. Followed by Rakunda and Tarunda.

Cast buffs

Cast buffs on your party members as well. Buffs can be in the form of attack power increase (Tarukaja), defense power increase (Rakukaja), and hit/evasion power increase (Sukukaja). These buffs can be accessed by Nahobino and any demons in your party.

Prioritize on landing Sukukaja first. Followed by Tarukaja and Rakukaja. You may also use Charge and Concentrate buffs to boost your damage even further if available.

Inflict Ailments such as Poison

Oni is susceptible to statuses such as Poison. While the boss is suffering from the Ailment, take advantage and set your debuffs and buffs.

Activate Magatsuhi skill

Unleash the Magatsuhi skill such as Omagatoki: Critical to boost your damage even further. Make sure to use it once debuffs and buffs are already set. Activate the Magatsuhi skill on Nahobino’s turn and you will have up to 8 possible actions against the boss.

Use Elec and Light skills against Oni

Oni is weak against Electricity and Light skills which Nahobino and his ally demons can capitalize on. The damage will be higher if the party is buffed with Tarukaja and Concentrate.

Use Almighty skills if available

In addition to elemental skills, you can make use of Almighty skills against the boss. Skills such as Life Drain ignore resistances and some provide additional healing through leech damage.

Use Phys skills only when buffed

Oni has resistance against Physical skills but can still be damaged. When it comes to Nahobino and other Physical damage dealers, you can still command them to deal Physical damage as long they are buffed with Tarukaja, Charge, and Magatsuhi skills such as Omagatoki: Critical.

Heal allies

Keep the party’s HP sustained by using healing skills. Especially when other party members are getting overwhelmed by enemy damage.
