Orthrus Strategies

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

Equip Shiranui Magatama

Shin Megami Tensei III: Nocturne HD Remaster - Orthrus Demon Boss Equip Shiranui Magatama

Before the battle, make sure the Protagonist or Demi-fiend is wearing a Shiranui Magatama. This Magatama nullifies Fire attacks.

Use Ice Skills

Shin Megami Tensei III: Nocturne HD Remaster - Orthrus Demon Boss Use Ice Attacks

Orthrus is weak to Ice attacks which Demi-fiend and other demons can capitalize. It can also inflict Freeze status by chance. The damage will be higher if the party is buffed.

Land Debuffs

Shin Megami Tensei III: Nocturne HD Remaster - Orthrus Demon Boss Land Debuffs

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

Prioritize on landing Sukunda/Fog Breath first. Followed by Rakunda and Tarunda/War Cry.

Cast Buffs

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

Prioritize on landing Sukukaja first. Followed by Tarukaja/Makakaja, and Rakukaja.

Boost Attacks

Shin Megami Tensei III: Nocturne HD Remaster - Orthrus Demon Boss Boost Phys Attacks

In addition to buffs, you can also use attacks further by using Focus (next Physical and Almighty deals x2.5 damage). This damage buff can be accessed by demons in your party.

Use Phys attacks

Shin Megami Tensei III: Nocturne HD Remaster - Orthrus Demon Boss Use Phys Attacks

Orthrus does not have resistance against Physical attacks so add party members that specialize in this attribute such as Archangel, Momunofu, and other demons. The damage is very effective when the boss is under Freeze status. If you don’t have them, just rely on your high-level demons and deal normal attacks instead.

Heal Allies

Shin Megami Tensei III: Nocturne HD Remaster - Orthrus Demon Boss Heal Allies

Keep the party’s HP sustained by using healing skills. Especially when other party members are using HP-consuming Physical skills.
