Wyvern bones

Wyvern bones are dropped by Skeletal Wyverns, very dangerous monsters found in the Asgarnian Ice Caves. Wyvern bones give 50 Prayer experience when buried, 175 when used on a Gilded altar (with two lit incense burners), and 200 experience when used to worship the Ectofuntus.

Wyvern bones can also be ground up into Wyvern bonemeal at the Ectofuntus and used to make Super prayer potions.

Players can quite rarely receive Wyvern bones as a reward from the Soul Wars minigame by selecting the Gamble option. Doing this might award a player with 16 Wyvern bones. These bones can also be looted from Zombie impling jars.
