Indy and Sallah find the Ark, and they’re able to lift it and carry it around without any Uzzah-esque zappy times, so at first it seems that this is just another artifact from a long past age. LifesLabyrinth- Previously in side arm of the way down in wyvern trench at 27. I am currently using waters, belials, lantern, and lostmauth. I'll have everything organized in the timestamps in the Command.
The artifact can easily be found inside the cave, simply by going Crystal Isles Landmarks: Landmarks with GPS and ADMIN Teleport Locators.
