Silverlight

Silverlight is a magical sword used in the Demon Slayer quest, which can be kept afterwards. The sword can only be obtained by completing the Trials of Body, Faith, and Mind during the quest. It is described as "a very shiny sword". This weapon cannot be made by players using the Smithing skill. If Silverlight is lost during or after the quest, it can be regained from Grüfeld Bach in the church north of the Varrock museum for free. It can be sold to the Wise Old Man for 80 coins.

Silverlight is dyed black during the course of the Shadow of the Storm quest and later becomes Darklight after killing the demon Agrith-Naar. Both Silverlight (not Black Silverlight) and Darklight can be mounted on the wall inside of a player's POH if he or she has a Quest Hall.

Silverlight is an extremely weak weapon when fighting non-demon monsters, with a Damage rating lower than that of a Bronze longsword. However, while fighting Lesser, Greater, Black or Abyssal Demons, along with demonic creatures such as Nechryael and Bloodvelds and Pyrefiends and even unique, high-level demons such as Zakl'n Gritch, Othanian, Holthion, Tstanon Karlak, Balfrug Kreeyath and the Ice Demon, Silverlight increases damage to approximately the same level as a rune longsword. However, Silverlight fails to have its special powers effective against minor demons such as Imps or demon hybrids such as Hellhounds. For example, what would normally be 110 LP damage against non-demons becomes 170 LP damage against demons.

However, because of Silverlight's low accuracy it is recommended that you DO NOT fight demons with Silverlight, unless you either can't wield rune weapons or any weapon that has superior stats to Silverlight. Prior to the Evolution of Combat, Silverlight was one of the strongest melee weapons available to a defence pure or any other player with only 1 Attack.

History
150 years ago, a Saradomist demon hunting ancestor of Grufeld Bach used Silver light to battle Delrith, and banish him back to his place of existance.

For the next 150 years, Silverlight resided in a crypt below the church in the Northeast of Varrock guarded by the spirits of the Bach family who had wielded Silverlight.

Trivia

 * Silverlight can be traded on RuneScape Classic.
 * It is possible to keep Silverlight after Shadow of the Storm; one way to achieve this is to have Silverlight in your bank while you use another to kill Agrith-Naar. Another way is to obtain Silverlight normally from Grüfeld Bach, even after completing Shadow of the Storm.  Also, if you have mounted your Silverlight in your Player-owned house before Shadow of the Storm, the monk at the start of the quest will exclaim and give you another one.
 * In RuneScape Classic, Silverlight was sold in the Legends' Guild. This was the only way to re-obtain it at that time, and due to complaints about this, Silverlight was removed from the Legend's Guild and it was obtained from Sir Prysin but since demon slayer was updated it can now be retrieved from Grüfeld Bach.
 * Silverlight is one of only 2 free-player weapons given an actual name, with the other one being Eek the Spider, and one of the few weapons in the entire RuneScape game to have been given one.
 * In While Guthix Sleeps, it is revealed that Movario, greatly fearful of the unnaturally powerful 'tormented demons', intends to seek out Silverlight in the event the sinister Lucien sets them on him, for "normal weapons will be only marginally useful, as the creature seemed to possess some sort of magical defense."
 * In RuneScape Classic, Silverlight will weaken a demon if it is used on the first hit.
 * Silverlight was graphically updated on 15 December 2009. Black Silverlight and its upgraded counterpart Darklight was updated along with the release of the 2009 Christmas event.
 * The Silverlight copy in Varrock museum did not change in the graphic update, it still had the look of the old Silverlight. This has been fixed.
 * originally you could own more than 1 Silverlight at a time, by doing the drop trick from Sir Prysin in exchange for 500 gp at a time, However this was changed when the demon slayer quest was updated and Players could retrieve silverlight from Grüfeld Bach. It is now impossible to do the drop trick since silverlight now has a "Destroy" option instead of a "Drop" option.
 * Due to the new Demon Slayer quest, older players that completed the original can have two Silverlight's.
