Buy RS3 Berserker necklace
The berserker necklace is a members-only necklace in RuneScape 3. When you wear it with an obsidian melee weapon, your damage goes up by 5%. This makes your obsidian weapons hit harder in combat.
The necklace also works with the Ek-ZekKil, a tier 95 weapon. With obsidian melee weapons, it can give a higher max hit than an Essence of Finality. The 5% boost also stacks with the Void melee set damage bonus.
The necklace has a damage stat of 60, a style damage stat of 34.5, and a prayer bonus of 3. It has no level requirements to wear, so any player can use it. It weighs almost nothing at 0.01 kg.
You can also combine the berserker necklace with the jal-tok-yt. This makes an am-hej or an am-zi. These are strong melee necklaces with passive effects that boost damage based on your Attack and Strength levels.
The necklace is made by casting Lvl-6 Enchant on an onyx necklace. Its melee stats are a bit stronger than the amulet of glory. It is a solid pick for any player who fights with obsidian weapons.
