Skeletal Wyverns are dangerous creatures. The below lists generally accepted strategies to make defeating skeleton wyverns easier. Note that a Slayer level of 72 is required in order to deal damage to Skeletal Wyverns (notwithstanding the effects of a poisoned weapon). Otherwise, eating a wild pie at 67 Slayer will do, though it will require constant reboosts. Quick travel tip is Fairy Ring Code •• to Mudskipper point. Run north from fairy ring to the dungeon entrance.
