Achromatic Balmung

The Achromatic Balmung is one of four Balmung upgrades as reward for completing the miniquest Koschei's Troubles. Unlike the Viridian, Crimson, and Cobalt Balmung, it was released two weeks later as a neutral colour. It is obtained by detecting curses on the gem during the miniquest and handing it to Kharshai to unlock a new memory. After enhancing the Balmung, one can right click and select "Toggle-colour" to remove the colour. The same process can be used to regain the colour.

When used on dagannoth, all enhanced Balmungs have a 45% bonus to hit chance, and deal 45% more auto-attack damage, or 35% against Dagannoth Supreme. With abilities, the extra damage is 22.5%, or 17.5% against Dagannoth Supreme.

Trivia

 * It has the same accuracy and better damage than 2h Barrows equipment when not used against Dagannoths or Wallasalkis.
