Break Impulse (ブレイクインパルス Bureiku Inparusu) is a melee-type spell cast by Chrono Harlaown in Magical Girl Lyrical Nanoha.

It focuses mana into a single melee swing or touch, allowing the caster's Device or bare hand to break hard objects by releasing shattering energy with frequency higher than their normal modes. When contacting the target, a few seconds have to be taken to calculate its normal mode. Therefore this spell requires not only magical ability but also combat agility. It is also mana-effective, consuming low mana but releasing high destructive power.[1]

Notable usesEdit

Break Impulse is first cast by Chrono in Nanoha (ep.12) in the Garden of Time to detonate a huge golem of Presea Testarossa.
