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[]

  • 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).
