Staff of light

The Staff of light is a unique drop from Ice strykewyrms. It is a one-handed magic staff requiring 75 Attack and 75 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 equipment. 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 (12.5%) 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.

Warning: The staff of light has a low alchemy value and will be lost to many other items that have a significantly lower GE price, so use caution when bringing the staff to dangerous areas such as PVP.

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 light. 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. While most magic staves offer a good crush attack bonus, the Staff of light has very good stab and slash attack bonuses. This is particularly useful against melee players who switch to Black d'hide armour to protect against mages, since slash attacks are very effective against d'hide.

Trivia

 * The Staff of light and the Godsword hilt have a similar examine information.
 * The top of the staff has an identical blade as the Saradomin sword and the bottom of the staff seems to be very similar to the Saradomin staff, which suggests it was an Icyene creation; however it does not count as a Saradomin-aligned item. If it does have a connection with icyene, it is unknown how the ice strykewyrm got a hold of them let alone their remote location from the god wars dungeon where the only icyene is left.
 * This item could not be lent out for the first 8 days after its release. However, an update on February 16 2010 changed that.
 * The Forge regent's special ability, Inferno, can be used to deactivate the special attack by unequipping the staff.
 * The drop rate is the same as that of an Abyssal whip from an Abyssal demon.
 * The Staff of light acts more like a glaive or halberd in function due to the bladed tip, as opposed to a staff.
 * The Staff of light special attack appears similar to the power Vanstrom Klause uses to defend himself, which many players believe holds some connection to the fact that Vanstrom may be a corrupted Icyene.
 * The special attack animation of this weapon may be a reference to the novel Lord of the Rings: The Fellowship of the Ring, where Gandalf breaks the bridge of Khazad-dûm with a similar motion, and it is described that a 'blinding sheet of white flame sprang up.'
