Skeletal Wyverns (Draconis ossis) are Slayer monsters that are the only monster to drop granite legs, as well as dropping the draconic visage. They can be found in the Asgarnian Ice Dungeon.

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.

Antifire, super antifire, and brightfire 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.

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

All my long hours of research have finally paid off! Today I discovered an ancient journal in the great library, which detailed a ceremony for giving life back to greater beasts after they have died! I shall finally be able to unravel the secrets of the Skeletal Wyverns!
