A hydrix bracelet is a bracelet made by crafting a gold bar and a hydrix at level 94 Crafting, giving 140 experience. Enchanting it with Enchant Level 6 Jewellery (requiring 87 Magic) or the enchant onyx tablet will turn it into a deathtouch bracelet, which gives best-in-class bonuses and a chance to reflect 25-50% of your opponent's damage back onto them. The plain hydrix bracelet has no bonuses.
