Demon King's Castle General Tips

Keep an Eye Out for Wall Gusts

There are marked walls around the castle that will produce a strong gust of wind each time it lights up. Time your movement so you don't get pushed far back, though there are cases that you need them to move around in some areas of the castle.

Demon King's Castle Bosses and Strategies

Chernobog

Recommended Level: 53
Tips and Strategy
Weak to Light Defend against the Magatsuhi charge

Chernobog mainly uses Physical attacks and Mamudoon. He is also weak to Light so bring demons like Anubis and Pazuzu (who learned Hamaon from Dominion).

Chernobog will use Omagatoki: Critical after gathering Magatsuhi. Use a Dark Dampener to block the following Mamudoon then for the critical hits, raise your defense/evasion and lower his attack/accuracy to avoid getting wiped out.

How to Beat Chernobog

Arioch

Recommended Level: 55
Tips and Strategy
Weak to Electric Use Light attacks on Decarabia Take out Decarabia first Bring Ice Dampeners

The fight will begin with Arioch summoning two Decarabia. Take these out first using Light attacks before targeting Arioch with Electric attacks.

We recommend bringing Nue and Kin-Ki to deal with Arioch, which are also found inside the castle. Both use Electric attacks and are great choices for attacker roles in this boss fight. As for Decarabia, you can bring Kushinada-Hime or Dominion, both having strong Light attacks and Recovery skills.

When Arioch starts gathering Magatsuhi, use an Ice Dampener to block the Mabufudyne that follows.
