Long-tailed Wyverns are Slayer monsters that require a Slayer level of 66 in order to be harmed. They reside in the Wyvern Cave on Fossil Island. Like with other Wyverns, an elemental, mind, dragonfire or ancient wyvern shield provides significant protection against their icy breath. These monsters require completion of the Bone Voyage quest to be assigned as a Slayer task.

Locations[edit | edit source]

There are two different wyvern caves - one where players can freely slay them, and one for those that have been assigned a Slayer task of Fossil Island wyverns. The task-only cave is reached via the trapdoor found in the Mushroom Forest, and the regular cave is found south of the Museum Camp. If a player attempts to attack the wyverns in the northern cave without a Fossil Island wyvern Slayer task, Weve (Steve's son) will stop them from doing so.

Drops[edit | edit source]

Drop rates estimated based on 95,043 kills from the Drop Rate Project, unless otherwise cited.

The average Long-tailed Wyvern kill is worth 10,316.

The average Long-tailed Wyvern kill while on a Konar task is worth 11,696.92.
