Etherilium Rolls are made at the Rolling Mill from an Etherillium Bar. Bars require 600 Geodes and 3 Firewood at the Blast Furnace. Rolls can only be sold to Otto von Tesla for 200 Image:SporeLarge.pngSpores. They serve no other purpose. Nidarian Guard members can use Geodes and various ores to make Etherillium Tubes, however, these Tubes cannot be made with Etherilium Rolls. It is impossible to turn Rolls or Bars back in to Geodes.
