Tiamat will elevate higher into the air and begin counting down to its signature move, D-A-R-KF-LA-RE, an upgraded version of Bahamut's Mega Flare which deals heavy damage regardless of the characters' Spirit stat. It is a Fire elemental attack.
In the game's American and European versions Eden can be drawn from Tiamat if the player did not draw it from Ultima Weapon earlier.
Characters can increase their elemental defense against Fire (such as by junctioningFire or Flare to Elem-Def) to reduce, nullify or absorb damage from Dark Flare. The battle can be made extremely easy by junctioning the characters to absorb Dark Flare, as Tiamat will be unable to kill the party, Dark Flare being its only attack.
[view·edit·purge]In Babylonian myths, Tiamat is a sea goddess and the embodiment of primordial chaos. She created all the Babylonian gods, then attacked them and was split in two by the god Marduk, who used her remains to create heaven and earth. In modern times, the game Dungeons & Dragons has Tiamat as a chromatic dragon, the Queen of the Evil Dragons and as such the opposing deity to Bahamut, who is a platinum dragon and the King of Benevolent Dragons.
