Deathtouched dart was an item that would kill almost any monster in the game with one hit. It was rewarded to players that had picked the Instakill Dart option from the fate cards received for having membership throughout August and September2012 as part of Sizzling Summer. A maximum of four darts could be obtained from the fate cards. When the dart was used it did not give any combat experience; however, Slayer experience would still be gained if used to kill an appropriate Slayer target. All unused darts were removed from the game in the beginning of 2013.
Deathtouched darts at one point did not kill Nex instantly. This bug lead to a lot of people dying and causing a grave glitch where you had to cast Telekinetic Grab to pick up your items from your grave.
The deathtouched dart hit splat from EoC is used by Vorago when he pushes you off the strip of land.
