How to Summon the Old One’s Army in Terraria: A Comprehensive Guide
The Old One’s Army is a unique Dungeon Defenders 2 crossover event in Terraria, offering a thrilling challenge and valuable rewards. Triggering this event requires a specific setup and understanding of the mechanics. Let’s dive into how you can summon the Old One’s Army and conquer its waves of enemies.
Initiating the Old One’s Army Event
To summon the Old One’s Army, you must first acquire an Eternia Crystal Stand and an Eternia Crystal from the Tavernkeep NPC. The Tavernkeep will arrive after you defeat a boss, and his stock changes as you progress in the game. Once you have these items, follow these steps:
- Prepare the Arena: The most crucial step is creating a suitable arena. You need a flat, open area with at least 61 blocks of space on either side of where you’ll place the Eternia Crystal Stand. This measurement is taken from the center of the stand, making a total of 123 blocks required in length. This clear space must be constructed of solid blocks, and not platforms. The stand cannot be supported by platforms; it must be placed directly on blocks.
- Place the Eternia Crystal Stand: Position the Eternia Crystal Stand in the center of your prepared arena. Make sure the ground beneath the stand is made of solid blocks and that there are no platforms supporting it.
- Activate the Event: With an Eternia Crystal in your inventory, approach the stand and press the ⚒ Use / Attack key. This action will place the crystal on the stand, initiating the Old One’s Army event.
- Face the Challenge: Be prepared for waves of enemies that will spawn from portals on both sides of the crystal, aiming to destroy it. The event consists of multiple waves, each more challenging than the last. Successfully defending the crystal will earn you valuable rewards, including Defender Medals that are used to purchase items from the Tavernkeep.

What is “Etheria” in Terraria?
Etheria is a randomly generated world seed that swaps the evil biome that appears in your world. (If your world is created as a crimson, Etheria will be corruption, and vice versa). It also changes the next step in progression to defeating the Eyes Of Oblivion.
How does Etherian Mana work in the Old One’s Army?
Etherian Mana is a special resource that is dropped by enemies during the Old One’s Army event. This mana is used to summon sentry towers, traps and to use any special weapons purchased from the tavernkeep during the event.

What happens if the Eternia Crystal is destroyed?
If the Eternia Crystal is destroyed, the Old One’s Army event will end prematurely, and you will not receive the full reward of Defender Medals. It is critical to protect the crystal from the incoming waves of enemies.
Can you speed up the Old One’s Army?
Yes! You can right-click the Eternia Crystal Stand during the event to adjust the spawn rate. Note that a lower spawn rate means faster spawns. The spawn rate gets reset after each wave. This feature allows for quicker progression and more intense battles.
What is the best weapon to use during the Old One’s Army event?
There isn’t a single best weapon, as it depends on your class and preferred playstyle. However, weapons like the Queen Spider Staff, Nimbus Rod, and Clinger Staff combined with sentries, provide strong coverage and damage.
What are some common mistakes to avoid when setting up the arena?
Avoid using platforms for the base of the arena; the stand must be on solid blocks. Ensure you have ample space for all the sentries and to maneuver around. Be sure you have a solid block area at least 61 blocks to the left and 61 blocks to the right of the stand.
