This article is about the Eternia Crystal "item". For the NPC, see Eternia Crystal (NPC).

The Eternia Crystal is an event-summoning item. When used in the Eternia Crystal Stand, the Old One's Army event begins. The Eternia Crystal is purchased from the Tavernkeep for 25 (pre-mechanical bosses), 1 (post-mechanical bosses), or 4 (post-Golem).

Tips[edit | edit source]

  • Players may wish to stock up on Eternia Crystals before defeating the mechanical bosses, in order to save coins.
  • Due to the price increase, it is possible to buy Eternia Crystals beforehand and sell them after the battles, netting a total profit of 55 per crystal (This no longer works on desktop. The price you sell the crystal for is based on the price you bought the crystal for regardless of which bosses you have defeated).
