The staff of light is a two-handed staff that requires 75 Magic to wield. It is obtained as a unique drop from ice strykewyrms, requiring 93 Slayer to kill. The golden parts of the staff can be recoloured at Solomon's General Store for a price of 2,000 Loyalty Points (one-time purchase).
The staff of light features a few special properties. When a combat spell is cast with the staff, there is a 12.5% (1/8) chance that the staff will negate the rune cost for that spell. This chance increases to 20% when wearing combat robes, and 50% when wearing battle robes. Additionally, the staff of light can be used as a more accurate alternative to the slayer's staff for casting Slayer Dart.
The Staff of Light was one of the most used staves before the Evolution of Combat, particularly before the introduction of the Polypore staff. Besides its strong Magic accuracy, it also had decent melee stats roughly equivalent to a dragon weapon (it required 75 Attack along with 75 Magic to wield), and had a special attack that would halve all melee damage taken for one minute, draining 100% of the bar. When using the special attack in conjunction with Protect from Melee or Deflect Melee, 90% of incoming melee damage could be negated.
The staff was the one primarily used with the Ancient Magicks. Its rune-saving effect was especially useful before the EoC, when spells such as Blood Barrage would cost over 2,000 coins a cast.
In addition, it is now also possible to have your staff of light in a different colour, by spending 2,000 Loyalty points, as of 21 September2011. The parts that are recoloured are the gold areas of the staff. Available colours for the Staff of light are green, baby blue, light red and a brighter yellow. According to Mod Rathe, the light yellow will be changed to be an inverted version of the original, where the blade and the middle part of the handle will be gold, while the two other parts of the handle will become silver.
