Reactor Purge (リアクターパージ Riakutā Pāji) is the ultimate defensive function of a mage's Barrier Jacket. When the damage taken by the caster exceeds the Jacket's limit, it will "detonate" to counteract a single attack, similar in principle to reactive armour on modern tanks.
In StrikerS, Reactive Purge (リアクティブパージ Riakutibu Pāji) is used instead for the same function.
- Reactor Purge is first seen in A's (ep.1) when Vita's Raketenhammer overpowers Nanoha Takamachi's defenses.
- In StrikerS (ep.17), Reactive Purge is activated by Subaru Nakajima's Barrier Jacket during her combat against Cinque, whose Overdetonation is too powerful for the injured Subaru. Presumably, such function is also loaded to the Barrier Jackets of other Riot Force 6 Forward members.
Jacket Purge is a similar spell/function which is initiated by the caster for specific purpose.
