Blast Calamity (ブラストカラミティ Burasuto Karamiti) is a mid-range joint attack spell cast by Nanoha Takamachi and Fate Testarossa, with Raising Heart Exelion's Exelion Mode and Bardiche Assault's Zanber Form. The spell exterminates its effective area with a storm of bullets and mana currents, and has another name known as Exterminating Combination (殲滅コンビネーション Senmetsu Konbinēshon), being one of the "N&F Combinations" in addition to Buster Shift (i.e. a joint attack arrangement using Divine Buster and Trident Smasher).
