The Jade demon statuette is the first of the six catacomb statuettes. It is found on its plinth that is located near the warped flies in the Lumbridge Catacombs, which can only be entered after completing The Blood Pact. An attempt to take the Jade demon statuette will result in a Warped Fly attacking you. However, you do not need to kill the Warped Fly to take the statuette. Xenia will want to buy it for 100 coins, claiming it reminds her of her first adventure, but it has no other use. If you do choose to sell it to Xenia, you will not be able to get it back from the Lumbridge Catacombs.
