Skeletal Wyverns have an often under-rated earnings potential, 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 200,000+ 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.
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 through all types of armour. Higher magic defence will make the max hit slightly lower.
Protect from Range is the suggested prayer to use on this fight due to the amount of range damage Skeletal Wyverns do, followed by Protect from Melee. While Protect Magic will reduce the amount of damage that the Skeletal Wyverns ice breath will do, it is not recommended for most players due to the amount of damaged being done by other styles of attack.
Note: Ranged below level 80 as well as Attack and Strength below level 80 WILL have trouble dealing any damage without a crushing weapon.
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!
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 April2010, 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.
There is a glitch where, when the wyvern melees you, it shows damage without the melee sign. However you can still block it with Protect from Melee.
Skeletal Wyverns used to be level 140, but after an update, their combat levels were raised to 198.
