Marmaros ore can be found in the Sinkholes Distraction and Diversion. When ores are the required resource, Marmaros rocks are sometimes scattered throughout the sinkhole dungeon. They require 20 Mining to extract ore from, and give 41 experience. The ore mined from them can be deposited at chutes or in the starting room to make progress towards the resources objective. When there rock sparkles, it will give two ore per attempt instead of one. Unlike normal marmaros ore ore, this ore does not stack in your inventory.
