Where to Find Ongyo-Ki

Ongyo-Ki Location

Ongyo-Ki can be found on B2 of Ikebukuro Tunnel, near the Asakusa Exit.

Ongyo-Ki will only appear if you've beaten the 3 other Oni: Sui-Ki, Kin-Ki, and Fuu-Ki.

Strengths and Weaknesses

Weaknesses

Weaknesses
None, but Phys attacks can go a long way.

Ongyo-Ki does not have any elemental weakness, however, using Phys attacks is useful for dealing damage.

Strengths

Attacks Dark, Phys
Void Light, Dark, Mind, Curse
Support Dragon Eye, Replicate, Tarukaja, Rakukaja, Sukukaja, Dekunda

Ongyo-Ki utilizes single-target Dark instakill skills, and devastating single-target Phys attacks, so we recommend bringing along demons that can block these types of attacks. Ongyo-Ki voids Light, Dark, Mind, and Curse attacks, so never use these types of attacks as you'll only be wasting your turn.

Likewise, Ongyo-Ki has six Support skills including Dragon Eye which grants Ongyo-Ki four extra turns, Replicate which Ongyo-Ki uses to replicate 3 more of itself, Dekunda which negates all debuffs applied, Tarukaja, Rakukaja, and Sukukaja.

How to Beat Ongyo-Ki

Locate The Ongyo-Ki with a Shadow Underneath Its Feet

The real Ongyo-Ki has a shadow underneath its feet. Target it immediately without attacking the replicates to eliminate all the replicates.

Only Visible on a Full Moon Phase

Ongyo-Ki's shadow will only be visible during a full moon phase. Make sure to wait a while for a full moon before initiating your fight with him so you can avoid the guessing game.

Don't Use AOE Attacks on a Group of Ongyo-Ki's

miss

Multi-target attacks on a group of Ongyo-Ki's will only be either blocked or dodged, causing you to waste your turn, making your party more vulnerable.

Don't Overinvest in Debuffs

dekunda

Ongyo-Ki can activate Dekunda which will negate all debuffs you afflict it with it. You can still use debuffs but be cautious!

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 Ongyo-Ki’s defense, to make it more vulnerable to your attacks.

Alternatively, you can use Fog Breath or Sukunda as these debuffs will decrease Ongyo-Ki's chance of dodging your attacks.

Buff Your Attacks

tarukaja

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.

No Resistance Against Phys Attacks

Phys Attack

Ongyo-Ki has no resistance against Phys Attacks, so don't hesitate to use these types of attacks on it.

No Resistance Against Magic Attacks Except for Light, Dark, Mind, and Curse

Force

Ongyo-Ki can block Light, Dark, Mind, and Curse attacks, but be comfortable using other elemental Magic attacks, as Ongyo-Ki cannot block or counter these.

Equip Anathema Magatama to Protect Against Dark Instakill

mudoon

We recommend equipping Anathema Magatama to nullify Ongyo-Ki's Dark Instakill skills. Likewise, summoning demons that can block this is also a sound choice.

How to Get Anathema Magatama

Have At Least One Dedicated Healer in Your Party

Summon demons that have Dia or Media or other variations of the skill, 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.
