Blast Fire (ブラストファイアー Burasuto Faiā) is a bombardment attack possessed by Stern the Destructor in the portable continuity, fired with Luciferion's Blaster Head. It is in substance a copy of Nanoha Takamachi's Divine Buster.

After Stern acquires her new powers upon reviving in The Gears of Destiny, fiery effect is added to the spell.

Notable usesEdit

Blast Fire is Stern's long-range bombardment attack in The Battle of Aces and The Gears of Destiny. Notably, the charged version in the latter is replaced by its enhancement spell Disaster Heat.


Disaster Heat (ディザスターヒート Dizasutā Hīto) is a fiery triple-bombardment attack developed after Stern acquires her new powers upon reviving in The Gears of Destiny. It is also her long-range charged bombardment therein, with shorter and decreasing ranges of fire than Blast Fire.[1]


  1. ^ In The Gears of Destiny special video, it is wrongly depicted as fired with Luciferion's Heat Head (with no mana wings instead of three for Blaster Head).
