Photon Lancer Genocide Shift (フォトンランサー・ジェノサイドシフト Foton Ransā Jenosaido Shifuto) is a variation of Fate Testarossa's Photon Lancer Phalanx Shift, modified by the Will of the Book of Darkness with her mana affinity in "wide-area" and "expansion". Whilst the original firing sequence is one-direction and broad, Genocide Shift is all-direction, like a wide-area cluster attack.
