Helm of the Black Demon

The Helm of the Black Demon is obtained after killing an unknown amount of black demons while wearing the Mask of the Black Demon. The helm has similar benefits to the mask, but does not provide bonus XP, extra damage, or double drops.

Benefits

 * Once per day (day resets at midnight UTC), while wearing the relevant mask, the next assignment the player receives will be black demons. They will still need to go to a Slayer Master that normally assigns these creatures – if they do not, the player will be told which Slayer Master assigns them. This does not work if they are in the process of setting up a co-op Slayer assignment.
 * Twice per day, this mask will teleport you directly to a choice of locations where black demons can be found.
 * Every creature killed is tallied while the mask is worn. The kill count continues to be tracked beyond this point, up to 999,999 kills.
 * A right-click option announces total kills of that creature,The announcement of total kills is not seen in the chat bar but is seen above your character by those around you. If the helm has yet to be unlocked, there’s also a message to say how many more kills are needed to do so.
 * After the helm version has been unlocked, the player is free to switch between it and the mask version, as a cosmetic preference only – this does not restore the Slayer experience and double drop effects to the mask.
