Uncut onyx
An Uncut onyx is required to make a amulet of fury, the ring of stone and the berserker necklace in Emps-World. It can be obtained in several ways: from the Shooting star distraction, by buying it for 32k Tokkul from the Tokkul exchange or as a rare drop by several monsters.
It can be cut on level 67 Crafting and with active membership, yielding 672 experience. If players cut the gem again, they will receive 15 Onyx bolttips, granting another 672 Crafting experience.
