This guide covers how to kill Fossil Island Wyvern in Old School RuneScape (OSRS): the best gear setups, prayers, inventory and locations. This OSRS slayer guide works for ironman and regular accounts, and covers whether each location allows cannon placement or safespotting, and whether this monster has a superior. It doubles as a money making guide, and will help both low and high level players complete their slayer task.
