Thanks. Almost there. You just need to add that they will not drop Chargebow or Staff of air if you have one in your bank not just your inventory (ie. backpack). Also this note applies to all monsters in the Lumbridge Catacombs ie. : Crpse Spider Warped Fly Crawling Corpse Torso Warped Rat Skeleton Warped Bat Corpse Archer Skoblin Corpse Mage
I have killed 1k of these. Changes to drops : Coins 40, 80 Air rune (3) - does not drop single air rune Does not drop Mind runes Also these will not drop the Chargebow or Staff of Air if you have one in your inventory or bank (this is also true for all monsters in the Lumbridge Catacombs).
