Mad necklace

Certain players may not be able to claim their necklaces; Jagex is manually adding accounts one by one to get the Mad May bonuses.

The Mad necklace is a necklace that can be obtained from Diango. After talking to Diango it is necessary to ask "Do you have anything else?" to redeem the necklace. On 1 June 2012 all players who had been a member for the entirety of May got a message after logging in stating "You have obtained the Mad Necklace! See Diango to claim it.".

After equipping a message states "You feel empowered by the festivities of May." and after unequipping a message appears stating "You are no longer empowered by the festivities of May." When equipping it a yellow glow goes around the player. When a player unequips the necklace, smoke will go around the player. The animations and messages stop once the charges in the necklace have been used up. When worn it gives 250k bonus exp in any skill and works the same way as the Sköll boots and Hati paws with checking the charge.

The experience multiplier does stack with Constructor's outfit, Golden mining suit, Lumberjack clothes and with a charged clan ring. It also stacks with player owned house altars. The necklace gives the full 2x boost to Summoning whereas on the Bonus XP Weekends, Summoning was only given a 1.1x boost.

It may be ill-advised to train combat skills or Slayer with this because it would give double exp in both the stat you are training and Hitpoints, this would use the charges up at a faster rate than if used on a single skill. As for Slayer the charges would be used on the combat skill you are using, Hitpoints, and Slayer as well.

The necklace does work for bonus Dungeoneering. It can be taken into the dungeon and equipped at the end to provide 2x Dungeoneering experience (tokens will not be doubled). Note: equip the necklace only when moving to the next dungeon if you want all the experience solely for Dungeoneering exp.

The necklace also works inside the Runespan, even doubling the experience received from locating the yellow wizard. Like Dungeoneering, points earned will not be doubled.

The necklace also works inside the Clan Citadel, doubling the XP from all plots.

When all the charges are used, the item is reduced to a cosmetic item similar to the Hati paws and Sköll boots.

Trivia

 * Unlike other bonus experience items, some static experience amounts such as the slayer reward from Bork are affected.
 * This is the first neck-slot item to have a graphical effect when equipped and unequipped
 * The description of the Mad Necklace references real rumours concerning the necklace. Many players misunderstood the description of the bonus that would be given at the end of Mad May, thinking that it would be an experience lamp worth 250,000 experience.
 * If the necklace is used at the point before running out of charge (even 1%) on a dungeon, it will still double ALL of the dungeon's experience, making dungeoneering a great choice for the last few charges of the necklace.
 * If the necklace has less than 1% of the charges remaining when you Check charges, the message reads "Your necklace has almost run out of power."
 * The examine info of the Mad Necklace is a reference to Mark Twain's quote, "The rumours of my death have been greatly exaggerated."
 * There is a graphical glitch where the Mad Necklace will not be shown on the player if the player is also wearing a Black platebody.
