Dark Bow

The Dark Bow is a two-handed ranged weapon used commonly by Ranged Pkers' because of it's special ability. It is the third most powerful bow, topped only by the two degrading bows: the New crystal bow and the Zaryte bow. It fires two arrows at once and applies to Bronze through Dragon arrows. It requires a Ranged level of 60 to use.

The Dark Bow is classified as a 'rare' item due to the item only being obtainable through another player, getting as a drop in PvP world (W2) or as a rare drop from a Dark beast. The dark bow cannot be crafted or fletched unlike most other bows.

Special Ability
The Dark Bow's special ability, named 'Descent on Darkness' fires two arrows at the target (must be dragon) which transform into two Black dragon heads, dealing increased damage with both shots, this uses 60% of the Specials Ability Bar. This is evidently very helpful when PKing because of the increased damage of both of the shots.

Trivia

 * In original Runescape, the Dark Bow used to have a defense bonus as well, making it a "Shield Bow" and the best Shield Bow in the game, but this was removed on entry to Soulsplit.
