Bararaq Saiqa

Balalark Saiqa (雷光剣 （バララーク・サイカ）, Bararāku.Saika, Lightning Sword) is a Metal Vessel of Sinbad. It gets it's power from Sinbad's Djinn, Baal. When Sinbad uses it, he draws lightning down from the sky. Once the lightning has been summoned and stored in the sword, it releases an enormous lightning blast able to fill the sky with light.

Trivia

 * The name of this spell is a corruption of the Arabic phrase صاعِقة بَرّاقة Ṣā3iqa Barrāqa, meaning "Flashing Lightning". The author forgot the a-vowel at the end of the adjective Barrāqa which would have made it agree in gender with the feminine noun Ṣā3iqa.
