The leviathan ring is a level 85 piece of jewellery from the Eastern Lands, unlocked through player-owned ports. Its name refers to the Leviathan, a dangerous sea monster. It has a unique ability: a 2% (5% for superior) chance per attack to reduce the incoming damage of that attack by 50% (rounded up).
The ring can be made at 90 Crafting in the port's workshop, using 80 pearls and giving 10,000 Crafting experience, after collecting the four parts of the leviathan ring eastern scroll. As with all craftable items in the workshop, boosts will not work.
The tradeable version degrades to dust after 100,000 charges of combat (a minimum of around 17 hours), vanishing after completely degrading. The superior leviathan ring, however, can be repaired.
The passive effect can activate on any incoming damage, including:
When the passive activates, it will reduce just the damage that activated it, not all damage taken that tick. A filtered chatbox message is given when the effect activates: The Leviathan ring reduces the damage of this attack by [damage].
