Staff of darkness

The Staff of darkness is a unique drop from Death strykewyrms. It is a one-handed magic staff requiring 80 Magic to wield. The Staff of Darkness can be used as a Slayer staff to cast the Magic Dart spell. It has stats comparable to Chaotic equipment. The staff has a special rune-saving ability; while wielded, there is a 1/4 (25%) chance that any combat spell cast with this staff will not use up any runes.

The rune-saving effect can be combined with a full set of Combat robes, improving the chance to 1/3 (33%). Battle robes can also be used, for a 1/2 (50%) chance of saving runes. Both robe sets can be earned as rewards from the Fist of Guthix minigame. Any time the staff does not save the player runes, the robes themselves will still have their usual chance of saving the player any Mind, Chaos, Death or Blood runes used by the combat spell the player is casting.

Trivia

 * The staff had a Special attack called Blackout. When activated, this special attack casts the chosen spell two times at once causing double the damage, also these attacks had a higher rate of hitting. This special attack took up 50% of the special bar.
