Klarwind's sparkle is all that reveals the spell
|Magic system||Ancient Belka|
|Japanese name||通信妨害 |
|First app.||A's (ep.9)|
Communication is possible within the field through Klarwind, but even Shamal herself cannot establish communication with parties outside the field.
Like most supportive spells, its spell name in Ancient Belkan language is not known in canon sources.
It is cast by Shamal in A's (ep.9) / The MOVIE 2nd A's when she helps hanging up the coats in the Uminari University Hospital, where she, Signum and Vita meet Nanoha Takamachi and Fate Testarossa, to hinder them from contacting the Administrative Bureau. On another hand, Zafira also cannot contact any of his fellow knights before he arrives at the battlefield.
