one of the easiest ways to make gold is mining right now shop needs quite a bit of fossils too and they are being bought at emporium shop.
in order to mine u need to go to area whre they can be found and buy a licence from the task master who will be in one of the entrances of the area. prices of licences are difrent in each area costing from 5k to 30k.
once u got the licence u jsut need to move about the area and pick the fossils from the ground as simple as that. if no agros dont even need to fight any mobs.
best and easiest way is just auto walk about the area and clicking g(pick all) whenever u see a fossil. a licence lasts for 15 min at lvl0 mining u will get avrege of 25-40 fossils as u lvl ur mining u will be getting more and more fossil.
