How to Beat Oni

Buff Allies Before Attacks


Use a buff like Focus or Tarukaja before using a Phys attack. This allows you to maximize your Phys Attack's damage output in the short turns you get.

Use a buff like Makakaja before using a Magic skill. This allows you to maximize your Magic Attack's damage output in the short turns you get.

Debuff Oni Whenever You Can

war cry

Use Tarunda or War Cry to lower its Phys/Magic Attacks. You will take less damage if you debuff its attacks.

Use Rakunda to lower Oni's defense, to make it more vulnerable to your attacks. Alternatively, you can use Fog Breath or Sukunda as these debuffs will decrease its chance of dodging your attacks.

No Resistance Against Magic Attacks


Oni has no resistance against any elemental Magic attacks, we advise you also to use boosted Magic skills into play to inflict more damage onto Oni.

Summon Demons that Have Nerve Attacks

Demons that can either stun or bind Oni are highly recommended to include in your party. Exploit its weakness to deal more damage and secure more turns for your team.

Equip Kamudo to Demi-Fiend

Kamudo Magatama will boost Strength, which will increase your Phys Attack’s damage output, and it will also boost Vitality which will increase your HP, helping you stay longer in this fight.

How to Get Kamudo Magatama

Have At Least One Dedicated Healer in Your Party

Summon demons that have Dia or Media so your party can restore HP as you move along the battle. This will be ideal especially in situations wherein you have no available Recovery items on hand.
