Guide:Nicholas the Traveler Farming/Roaring Ether Heart

Be warned this item has an extremely low drop rate
 * Collecting 1 Roaring Ether Heart per gift
 * Located in The Mirror of Lyss on the western side of the central pool, by the collector (Vabbi)
 * Farm  Roaring Ethers.
 * Methods:
 * Use a perma with Sliver Armor and Radiation Field to kill the Roaring Ethers along the eastern side of the Mirror of Lyss. Kill the dervishes first or they will kill you with their burning. Use the resurrected Ethers from previous groups to power sliver armor through the next group. Route takes about 9 minutes in hard mode to kill 15 Roaring Ethers.
 * SoS ritualists can also farm Roaring Ethers, although it is slow and more dangerous than perma farming. Consider bringing Healing Breeze or another self heal to counter health degeneration and Wastrel's demise.
