A hydrix necklace is a necklace made by crafting a gold bar and a hydrix at level 90 Crafting, giving 135 experience. Enchanting it with Enchant Level 6 Jewellery (requiring 87 Magic) or the enchant onyx tablet will turn it into a reaper necklace, which grants a stackable 'reaper buff' upon each hit, granting 0.1% hit chance buff in all styles, stacking up to 30 times (for a total of 3.0%). The plain hydrix necklace has no bonuses.
