Trivia

 * In Norse mythology, Balmung (or Gram) was the magical sword of the hero Sigurd or Siegfried as known in Germany.
 * Wallasalkis are affected by the Balmung effect as if they were Dagannoth, but interestingly don't count toward a Dagannoth slayer task.
 * The knock-out aura does work with the Balmung.
 * This weapon does not have the same effect on the Spirit dagannoth summoning familiar.
 * It has the same accuracy and better damage than 2h Barrows equipment when not used against Dagannoths or Wallasalkis.
 * Cobalt is a grey metal, although Cobalt blue is a common blue pigment.
