Skeletal Wyvern



Skeletal Wyverns (Draconis Ossis) are very dangerous monsters that can drop Granite legs and the rare Draconic visage. Level 72 Slayer is required to kill them. An Elemental shield, Mind shield, Body shield or Dragonfire Shield must be equipped when fighting wyverns, or else the player will be hit for very high damage. They are the lowest-levelled monsters to drop the Draconic visage, though it's debatable if they are the weakest.

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

Skeletal Wyverns are often under-rated by some mid to higher levelled players as players on a slayer task with over 85+ range, 68 summoning and 80+ defence with full slayer helmet and using ranging/defence potions can easily make 200k+ an hour including banking time. They are also a great source of crimson charms, although there are many (easier) alternatives if one is not on a slayer task.

Strengths and weaknesses
Players must equip an Elemental shield, Mind shield, Body shield or Dragonfire Shield (Anti-Dragon Shield does not work) while fighting these or they will be hit for very high damage, along with having their stats heavily reduced. Players can also use the Protect from Magic Prayer or the Deflect Magic Curse to lower the max hit of the ice breath attack if they are not wearing a shield, which negates stat loss as well as lowers the max hit to 200. However, this is nowhere near as effective as the shields. Wyverns have high Defence, Attack, and Life points, making them very challenging opponents. Wyverns attack with either melee or range, as well as a freezing-breath attack. This attack can freeze players in a fashion similar to the Ancient Magicks ice spell. Contrary to popular belief, the accuracy of this breath attack is NOT affected by armour. It will hit regardless of your armour; wearing the shields is the only real option that can affect their breath.

Defensively Sketetal Wyvern has a weakness to crush, followed by slash, while stab being most resistant. However the best weapon is debatable since there are a lack of good 1-handed crush weapons which are either too slow (like battleaxes) or too weak (like maces). Therefore many people choose slash weapons such as a Abbysal Whip since while they are slightly more vulnerable to crush, the whip has a speed and attack bonus advantage to almost every one-handed crush weapon. If a player dosent have a Whip, Wyvern are also vulerable to Longsword's slash attacks, primary Chop. For special attacks a Dragon Longsword special attack is surprisingly very effective. Dragon mace special can be used as a alternative but not nearly as effective as the longsword's.

On the offensive part, the Wyverns uses ranged the most, follow by ice-breath, while melee is used least often. It is recommended to kill these wearing full proseltye armour along with other high prayer boosting gear such as Soul wars cape, amulet of fury etc. The player should use Protect from Ranged to minimize most of their damage. Best weapon would be a Abbysal whip, followed by Dragon longsword followed by Dragon Battleaxe (on smash).

Alternatively, players can simply tank all of their ranged and melee attack and survive a trip using only food and a super set. This will require Barrow armour and a Dragonfire Shield as well as other high level gear. However, they should still bring one or two prayer pots to use Piety or Turmoil which really speed up a difficult kill.

Despite being skeletal creatures, they are not classified as undead but rather animated piles of bones. As such, wyverns are not vulnerable to the effects of the Salve Amulet or the spell Crumble Undead. Players should also note that the Fist of Guthix Dragon Slayer Gloves do not give bonuses when fighting them even though they drop the Draconic Visage and the Antifire potion has no effect on the wyvern's ice breath attack. Ice gloves do not help avoid their icy breath either.

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.
 * Skeletal Wyverns are mentioned in Tarn's diary:


 * The horns on the sides of the Skeletal Wyvern's skull look remarkably similar to those on the side of the dragon heads in the dragon forge.


 * On the 23 April 2010, some players experienced a graphical glitch which caused all wyverns in view to disappear; however, their life bar and shadow remained, making it look as if players are fighting the air.
 * Before the skeletal wyvern's attacks were updated, there was a glitch in which Protect from Melee would block both its melee attacks and breath attacks.
 * Skeletal Wyverns may drop Snakeskin chaps, which when on the ground resemble Granite legs. This is likely another prank by Jagex such as Dust Devils dropping red d'hide vambraces which resemble the Dragon Chainbody.
