Blitz Action first appears in Nanoha, and is later replaced by Blitz Rush (for aerial battles) after Bardiche receives a cartridge system upgrade. While both spells are designed for short range, another spell named Sonic Move is also developed for long range high speed movements. By the time of StrikerS, Blitz Action's supportive function is fine-tuned for body movements such as wielding and footwork, in addition to only short range general movements. It is also Fate's choice on the ground or indoors.
