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 that 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 junctioningFiraga 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]Tiamat is a primordial goddess of the ocean in Mesopotamian religion. 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.
