Phantom Blazer (ファントムブレイザー Fantomu Bureizā) is Teana Lanster's most powerful spell in StrikerS, but also the slowest to cast. Categorized as a "long range sniper cannon" attack, instead of a magic loop it makes use of a "target ring" and, when firing at long range, a laser sight. As revealed in Sound Stage X, Nanoha has taught Teana her mana collection bombardment skills supposingly as an upgrade of Phantom Blazer. Nanoha explains she would do so because she wants Teana to follow how she would have trained.
