The berserker necklace is an onyx necklace enchanted by the Lvl-6 Enchant spell. When worn, it increases the amount of damage the wearer does when wielding an obsidian melee weapon (Toktz-xil-ak, Tzhaar-ket-om, Tzhaar-ket-em, or Toktz-xil-ek) by 20%. However, in exchange it lowers the wearer's melee accuracy and the player's defences against all combat styles. This bonus stacks with the bonus provided from wearing the Obsidian armour set (helmet, platebody, and platelegs). It also stacks with slayer helmet and Void Knight equipment.
Players can attach a Berserker necklace ornament kit, obtained from hard Treasure Trails, to create a Berserker necklace (or). This is only cosmetic, and does not affect the necklace's stat bonuses. It can be dismantled, returning the necklace and ornament kit.
