Notes |
See Rock Of The Ages for the PER needed for each type of marble, and note that anyone can raise their perception by blessing a PER WaterTower.
For example, with a WaterTower PER boost, Bifa is able to prospect for: Oyster Shell Marble, Yellow Alabaster, Mud Granite, White Travertine, Canary Granite, Night Granite, Grey Star Marble, Green Sun Marble, Rose Alabaster and Cherry Travertine.
Lastly, a Stone Quarry costs: 25 slate, 15 rope, 2 pulley, 100 bricks
