Staff of light

The Staff of light is a unique drop from Ice Strykewyrms. It is a magic staff requiring 75 Attack and Magic to wield. The Staff of Light can be used as a Slayer staff to cast the Magic Dart spell. It has stats comparable to Dragon weapons. The staff has a unique +15% magic damage bonus, 5% more than all other magic damage-boosting staves. The staff has a Special attack called Power of Light . When activated, this special attack reduces any melee damage that is received by 50% for one minute. If the staff is unequipped during this time, the effect is lost. The staff also has a special rune-saving ability; while wielded, there is a 1/8 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 1/5 (20%). 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. This effectively causes 65% of the runes to be saved with Battle robes and 23.5% of the runes to be saved while wearing Combat robes.

Combat and magic styles
The Staff of Light gives the third best magic attack bonus for any one handed weapon, after the Master wand (+20) and Zuriel's staff or Corrupt Zuriel's staff (+18). The Penance trident has a magic attack bonus equal to that of the Staff of Loght. The Staff of Light gives the single best magic damage bonus, 5% more than all other staves with a magic damage bonus. Together with Zuriel's staff (or the corrupt version) it has the best strength bonus for any magic staff.
