Skeletal Wyvern

Skeletal wyverns are NPC's located in the high level Slayer dungeon. They are a high level Slayer task but are commonly killed for their bones. The Skeletal Wyvern used to be a very popular monster to capture as it was highly effective to use in the minigame Soul Wars. It is much more common to find players using Frost Dragons, Borks, or King Black Dragons now.

Location
Locate the Dungeon teleport in the spellbook, click 'next' until Slayer Dungeon is visible, click it and then select 'High level dungeon'. Wyverns are located South-East from the teleport spot.

Protection
Skeletal Wyverns require an Elemental shield or Slayer helmet equipped in order to attack them. Players can acquire both the Elemental shield and Slayer helmet from Vannaka, located near the Lumbridge yaks; one of the Training Locations.

Fighting Tactic
When fighting a Skeletal wyvern, the recommended gear is anything that is high in Magic defence (Karils/Black d'hide, Armadyl, Pernix or Void). Wyverns are usually crowded, so it is recommended to change worlds for the best killing experience. Another extremely effective method for fighting wyverns is wearing a slayer helmet which negates the requirement of having to wear an elemental shield meaning you can use a dragonfire shield.

Trivia

 * Wyvern Bones are the second best bones for Prayer experience in the game, just behind Frost Dragon Bones.
