Wyvern

Wyverns are draconic monsters in the Asgarnian Ice Dungeon. They were first revealed at RuneFest 2015, after being pitched on RuneLabs and being one of the November poll winners. They require level 96 Slayer to be killed. Wyverns reside in an icy cavern beneath the area the skeletal wyverns reside in. They also have an elite version.

How to get there
Go to the Asgarnian Ice Dungeon, enter the skeletal wyverns' cave, and go to the south-west corner. There will be rope in a hole in the floor, descend down the rope and that is where the living wyverns are.

The quickest methods of reaching the cave are by using the Port Sarim lodestone, or teleporting to the Asgarnian Ice Dungeon resource dungeon with a Hoardstalker ring.

Mechanics
Upon entry, the bitter cold of the cavern will start to take effect. As the player loses heat, the screen will begin to show ice marks, indicating that the player is getting colder. The chill of the cavern will apply 3 separate effects to a player as they stand in the open cold. These effects are reset by leaving the cavern and can be mitigated by lighting fires on fire remains scattered throughout the cavern.


 * Warm: Wyvern poison damage increased.
 * Cold: Wyvern attack damage increased.
 * Coldest: Player will be constantly stunned at 8–10 seconds per stun; it is highly advised to light a fire or get out of the cavern immediately if this happens.

The wyverns have various ice breaths, their normal ones (used by their skeletal brethren), and a poisonous one. Whenever the wyvern uses the poisonous ice breath, a message will appear and say "The wyvern's poison corrodes into your bones." The poisonous dragonfire's magic damage can be negated with wyrmfire potions, but does not affect their poison damage. Unlike other poison sources, it cannot be cured from antipoison++, the Anti-poison totem and the Poison Purge aura. However, antipoison++ will reduce the poison's damage by half if used, but like all monsters capable of poisoning, it will not last the full 12 minutes.

It is possible to tackle Wyverns with quick prayer switching, as their ranged attacks produce green smoke and magic attacks produce blue smoke. Appropriate prayer switching will nullify half of all incoming damage, although this method requires isolating the wyverns for 1-v-1 combat. Standing one square away (melee distance) will cause that wyvern to only attack with melee (which suggests a mage setup with praying protect/deflect melee).

Charms
4 charms are dropped at a time.

Trivia

 * Wyverns are referred to as living wyverns in the beast tab kill count interface.
 * There is a glitch where if assigned wyverns, when quickchatted it will say you are assigned "Nothing", including if they are preferred or blocked. This does not affect the built-in slayer counter however.
 * If multiple players attack a single wyvern, no loot will drop for either player.
