Silverlight is a demonbane sword that is very effective against demonic creatures. It is first obtained during the quest Demon Slayer, where it is used to defeat Delrith. During Shadow of the Storm, Silverlight is dyed black using black mushroom ink, and later becomes Darklight after it is stained with the blood of Agrith-Naar.
If it is lost, it can be bought back from Sir Prysin for 500gp at Varrock palace. It can also be sold to the Wise Old Man for 80gp. It is possible to obtain multiple Silverlight swords by dropping them and buying more, or by getting it mounted in a player-owned house at level 42 Construction.
When using Silverlight to fight demons or Vampyres, the player's maximum hit is increased to approximately the same level as a rune longsword; however, its accuracy remains the same.
Warning: Dying Silverlight black will consume all copies of the sword in your inventory, leaving you with only one dyed sword. You will need to bank or drop any extra swords before dying one.
After completion of Shadow of the Storm, Silverlight will become unobtainable unless switching to a Free-to-play world to purchase one.
- The dyed black version of the sword can be created at any point after Shadow of the Storm, provided the player obtained multiple Silverlight swords using the drop trick.
- Despite being black in colour, the dyed sword is not dubbed "Darklight" until after it has been used to slay Agrith-Naar.
