Hexcrest

The Hexcrest is a unique Slayer item dropped by Jungle strykewyrms. In order to equip it, a player must have a Magic level of 20, a Defence level of 10, and a combat level of 40. It boosts the player's magic damage by 15% against their slayer task monsters. It can be combined with the Focus sight and Slayer helmet to form a Full slayer helmet. With the Staff of light, a 7 level boost from an Extreme magic potion, Overload potion or Wolpertinger, being in Kuradal's Dungeon and wearing a Ferocious Ring, and a Hexcrest or Full slayer helmet worn against an assigned slayer monster, the theoretical (if all of those things stack, which is not confirmed at the moment) damage percentage boost would be 51%. For already powerful spells like Fire Surge or Ice Barrage, the resultant Magic damage could be approximately 422 or 453, respectively, on a slayer task with a 51% boost. A Max hit of 1096 is possible on Ice strykewyrms using Fire Surge. Also, adding an arcane stream necklace could boost this bonus to 66%, if the items stack. Hexcrest could be used alone without the full slayer helmet, but it does not give the 51% damage boost.

This item is NOT lendable.

On the day this item was released, people were paying an upwards of 25 million coins, utilising junk trading, to buy them. It crashed in the next few weeks in the Grand Exchange, falling over 60% in 4 weeks.

Trivia

 * As of 28 March 2010, there is currently a glitch in the Grand Exchange market watch that oversizes the hexcrest's icon. The icon is so large that it overflows off the square and parts are not visible.
 * The boost of a Hexcrest does affect the magic attack of Saradomin sword's special attack and the Dragonfire Shield's fire blast.
 * The Hexcrest is worn like a crown when walking around but your chathead has it worn like a headband.
