Death wings are flying monsters that appear in the Legends' Quest. The death wings are located in a remote area, and have no drops, so very few players train on them. Killing a death wing is one of the hard tasks in the Karamja Diary.
They can be killed for bat Slayer tasks, and they give the highest experience out of any monster in this category.
They also count for ghost slayer tasks.
Death wings can only be found in the Viyeldi caves, which is unlocked during the Legends' Quest. To reach them, players should bring one or more lockpicks, a machete, any axe and any pickaxe. The dungeon can be found in the north-west of the Kharazi Jungle by searching the mossy rocks, after which the player should search the bookshelf north of Ungadulu and choose to squeeze through there, picklock the ancient door, mine the rocks and open another door to reach the death wings. Death wings can also sometimes be found inside barrels in the dungeon.
Drop rates estimated based on 250 kills from the Old School RuneScape Wiki drop log project, unless otherwise cited.
