Eternia Crystal (NPC)

The Eternia Crystal NPC is a background object that is the centerpiece of the Old One's Army event.

Right-clicking the Eternia Crystal Stand with an Eternia Crystal in the player's inventory will place the Eternia Crystal on the stand. After a 5-second countdown, the Eternia Crystal (now considered an NPC) must be protected from waves of enemies from the Old One's Army who will prioritize attacking it. If the Crystal is destroyed, the event ends in failure. If it is kept "alive" until all waves are cleared, the event is won.

Both the Eternia Crystal and its stand are purchased from the Tavernkeep for and  respectively. A long, flat area is required in order to place the Eternia Crystal successfully and summon the event; otherwise, the Eternia Crystal will reject the area and pop out of the stand, able to be picked up as an item once again.



Trivia

 * The crystal's map icon is the same as its inventory sprite.
 * The crystal's sprite will have cracks in it as its health decreases.
