The Three Keys General Tips

Komagata Leyline Fount Location

The path leading to Komagata's leyline fount and Odin is easy to miss but once you find the entrance, you won't have any more problems getting to the top.

From the Asukasa Main Street fount, head west until you find a Sandman with the subquest The Sleeping Sands. A little more to the west is an NPC Macabre, marking the entrance of the path you're looking for.

From there, use the blocks and the moving stairs to get to the top where you can find the leyline fount and Odin nearby.

Destroying the Abscess of Ueno Park

Cybele and Scathach are both weak to Electric but watch out for their Fire and Light attacks. Bring demons like Nue and Titania to match their weakness. Titania can also provide healing with Diarahan and inflict Sleep with Lullaby.

Unlocked Miracles

Divine Garrison IX	Fire Mastery V	Ice Mastery V
Electric Mastery V	Force Mastery V	Majestic Aura

Destroying the Abscess of Shinobazu Pond

Skadi, Atavaka, Barong, and Siegfried will face you in this Abscess, each having different affinities.

Tao can spam Megidola to ignore enemy resistances as well as use Hamaon to target Siegfried's weakness. Ananta is also a good choice for this battle as it can block/resist most of the enemies' attack and use Ice Dracostrike on Atavaka to gain extra turns.

Avoid using Physical attacks against Siegfried as he can absorb them.

Unlocked Miracles

Prayer of Agility	Prayer of Luck	Light Mastery V
Dark Mastery V	Ailment Mastery V

Destroying the Abscess of Kuramae

Yatagarasu, Throne, and Mitra are guarding this Abscess and unlike the previous team, they have some similatrities in weaknesses.

Mitra is weak to Ice, Yatagarasu is weak to Dark, while Throne is weak to both. This Abscess is also easier than the one in Shinobazu Pond since they have lower levels.

Just don't use Light attacks on any of them as they will simply block them.

Unlocked Miracles

Deathly Aura IV	Healer's Hospitality II	Almighty Mastery IV
Physical Mastery IV	Art of Essences III

Destroying the Abscess of Asakusa

Rangda can be very annoying as it naturally reflects Physical attacks and can cast Makarakarn to reflect the next incoming Magical attack. Use Almighty attacks like Sakanagi or "Piercing" attacks like Hell Thrust to counter these.

Both Girimekhala and Garuda can learn Hell Thrust. Girimekhala can be found just east of the Abscess while Garuda can be obtained through Fafnir and Nue's fusion.

Unlocked Miracles

Merchant's Hospitality II	Recover Mastery III	Support Mastery III
Prayer of Strength	Prayer of Magic

Destroying the Abscess of Azumabashi

Yamata-no-Orochi can block both Ice and Fire but is weak to Electric. Since it mostly uses Physical attacks, Girimekhala is a perfect demon for this fight as it can reflect Physical skills. Bring demons like Titania and Ananta to target his weakness and gain extra turns.

Unlocked Miracles

Demon Proficency IV	Divine Proficency IV	Almight Mastery V
Physical Mastery V

Destroying the Abscess of Motoasakusa

This is an odd but dangerous Abscess as it inhabits a Slime, a Pixie, an Onmoraki, and a Preta. These are early game demons but in this fight, they are all lv99 and has a total of 8 turns. Skip this Abscess for now and go back when you already built a team that can take them on.

Summoner's Hospitality III

The Three Keys Bosses and Strategies

Abdiel

Recommended Level: 58
Tips and Strategy
Weak to Dark Give Nahobino resistance to Light Bring Fire Dampeners

Abdiel will focus her attacks on Nahobino and will only hit your allies when she uses Light's Descent and Maragidyne.

Fuse Nahobino an essence that can block Light attacks like Titania and Atavaka, especially if your current affinity is weak to Light. For your demon allies, bring those who have Dark skills and are not weak to Light like Atavaka, Lahmu, and Flauros.

Use a Fire Dampener when Abdiel starts gathering Magatsuhi to block the Maragidyne that follows.

How to Beat Abdiel

Odin

Recommended Level: 72
Tips and Strategy
Weak to Force Have Rangda act as tank Bring Ice Dampeners

A lv69 Lilith and a lv68 Skadi can learn Null Elec and Null Ice respectively. Fuse the two into Rangda, teach it Taunt through essence fusion, and make it your meatshield against Odin.

Mot is a good choice for the attacker role as long as you give it a Resist/Null Elec through essence fusion as well.

Use an Ice Dampener when Odin starts gathering Magatsuhi to block the Mabufudyne that follows.

How to Beat Odin

Zeus

Recommended Level: 72
Tips and Strategy
Weak to Force Give Nahobino resistance to Physical and Electric Bring Elec Dampeners

At this point, you can summon demons that can deal more damage with their Physical attacks than using Force attacks to target Zeus' weakness while also being resistant to Electric like Seth, Mara, and Thor. Though not resistant to Electric, Futsunushi is also an excellent choice for this role especially with his Phys Pleroma. You can obtain Futsunushi by completing In Defense of Tokyo.

Use an Elec Dampener when Zeus starts gathering Magatsuhi to block the Maziodyne that follows.

How to Beat Zeus

Vasuki

Recommended Level: 72
Tips and Strategy
Weak to Fire Have Rangda act as tank Bring Ice Dampeners

We recommend bringing Surt or Adramelech to target Vasuki's weakness to Fire. Though slightly weaker than the two, you can opt for Yamata-no-Orochi instead since it can block Ice.

Similar to our strat against Odin, you can fuse a Skadi with Null Ice and another demon into Rangda, teach it Taunt through essence fusion, and make it your meatshield against Vasuki.

Use an Ice Dampener when Vasuki starts gathering Magatsuhi to block the Mabufudyne that follows.

How to Beat Vasuki

Beelzebub

Recommended Level: 72
Tips and Strategy
Weak to Fire Bring Rangda for Taunt Bring Wind Dampeners

We recommend bringing Mot or Adramelech to target Beelzebub's weakness to Fire.

Similar to our strat against Odin, you can fuse a Skadi with Null Ice and another demon into Rangda, teach it Taunt through essence fusion, and make it your meatshield against Beelzebub.

Use a Wind Dampener when Beelzebub starts gathering Magatsuhi to block the Zanbarion that follows.
