How to Beat Tiamat

Tiamat Strategy
Prevent Boss From Exploiting Weakness Recruit Demons That Reflect and Absorb Elements Prioritize Defeating the Enemy Minions Use Phys Dampeners to Nullify Collapse Ray Use Dekaja or Purge Charm to Nullify Luster Candy

Prevent Boss From Exploiting Weakness

Elemental attacks will come flying at you in variations due to Tiamat's access to high-level elemental skills. Ensure that your party possesses the right skills by inheriting them or fusing demons to counteract the boss' elemental attacks.

Recruit Demons That Reflect and Absorb Elements

Ensure that you and your party can absorb and reflect elemental attacks thrown at them so you can endure much longer during the boss fight. This will help negate some attacks received by Tiamat, as well as lessen the pressure inflicted by the boss.

List of Demons

Prioritize Defeating the Enemy Minions

One way to approach the fight is to prioritize defeating the enemy minions during the boss battle, as Tiamat will reduce 2000 HP from its own body to revive the fallen minions in battle. Since Tiamat has no weaknesses, this strategy will reduce a substantial amount of its HP.

Mediarama Will Be Cast After Tiamat Reaches 1/4 HP

Once Tiamat reaches 1/4 of its HP, it will cast Mediarama to heal itself and its minions in battle. Be sure that when this state is reached, all enemy minions are dead so that they won't receive any recovery from Mediarama.

List of Recovery Skills

Use Phys Dampeners to Nullify Collapse Ray

Tiamat will use a powerful physical skill called Collapse Ray after it fills out its Magatsuhi gauge in battle. Nullify this by bringing Phys Dampeners, as the attack will surely kill everyone in your party when successful.

Phys Dampener Effects and How to Obtain

Use Dekaja or Purge Charm to Nullify Luster Candy

When Tiamat reaches the near depletion of its HP, the enemy minions will use Luster Candy to buff all its stats and increase the severity of their attacks. Prevent this by casting Dekaja or using Purge Charm to nullify the buffs given by Luster Candy.
