Skeletal Wyvern

Skeletal Wyverns (Draconis ossis) are Slayer monsters that exclusively drop granite legs, as well as the draconic visage.

Level 72 Slayer is required to kill them. An elemental, mind, body, cosmic, chaos, or Dragonfire shield (not an anti-dragon shield) must be equipped when fighting wyverns closeup, or else the player will be hit for very high damage.

Super antifire potions do NOT work against their icy breath, unless it is combined into a Wyrmfire potion. The Protect from Magic prayer or Deflect Magic curse will reduce damage taken from the breath to less than 200, similar to Dragonfire. They are only found in the Asgarnian ice dungeon, in the chamber accessed from the southern wall of the icy area.

Killing a Skeletal Wyvern is one of the hard Falador Tasks as well as for the wish list of the Odd Old Man in the Fur 'n' Seek quest.

Since the Evolution of Combat, Skeletal Wyverns have arguably become easier to kill, though their damage capabilities can still pose a threat. Players on a slayer task with over 85+ magic, 68 summoning and 80+ defence with full slayer helmet and using super magic/defence potions can easily make 450,000+ coins an hour, including banking time. They are also a good source of crimson charms, although there are many (easier) alternatives if one is not on a slayer task.

Combat
Wyverns attack with melee, ranged or their unique ice-breath attack. This attack can freeze players, and they will be stunned as well, so escaping is not possible unless Freedom is used to break free (this is currently glitched and will not free the player like it otherwise should, although it does break the stun).

If a player is not wearing one of the shields they will be hit for very high damage. Contrary to popular belief, armour does not affect the accuracy of the ice-breath attack, the ice-breath will hit regardless of armour.

Wyverns will use a ranged attack both when players are attacking from a distance and when they are attacking within melee range. Their melee attacks are comprised of a bite and use of the tail.

Trivia

 * A Wyvern is a legendary winged reptilian creature with a dragon's head, the hindquarters of a snake or lizard with two legs or none, and a barbed tail.
 * Even though the salve amulet has no effect on Skeletal Wyverns, they are mentioned in Tarn's diary:


 * The horns on the sides of the skull of one of the Skeletal Wyverns look remarkably similar to those on the side of the dragon heads in the dragon forge.
 * There is currently a glitch where using the Freedom ability will not properly free the player from being frozen by a wyvern's breath. It has not been fixed yet.
