What are the requirements for the Old Shaking Chest to appear in Terraria?

The Old Shaking Chest is a unique and rare event in Terraria that can be both exciting and challenging for players. This event is tied to the Old One's Army, a special invasion-style event that occurs when the player interacts with an Eternia Crystal Stand. The Old Shaking Chest is a reward chest that appears after successfully defending the Eternia Crystal during the Old One's Army event. To understand how to make the Old Shaking Chest appear, it is important to first understand the mechanics of the Old One's Army event and the steps required to trigger and complete it.

The Old One's Army event is divided into three tiers, each corresponding to different stages of game progression. The first tier is accessible after defeating the Eye of Cthulhu, the second tier after defeating any mechanical boss (The Twins, The Destroyer, or Skeletron Prime), and the third tier after defeating Golem. To start the event, you need to purchase an Eternia Crystal and an Eternia Crystal Stand from the Tavernkeep NPC. The Tavernkeep will only appear after you have defeated the Erebus or the Goblin Army, and he sells these items for Defender Medals, which are earned by participating in the Old One's Army event.

Once you have the Eternia Crystal and Stand, you can place the Stand in a suitable location. It is recommended to build a flat arena with platforms and walls to help defend against the incoming waves of enemies. The Stand should be placed in the center of this arena. When you interact with the Stand and place the Eternia Crystal, the event will begin. You will need to defend the Crystal from waves of enemies, and if you successfully protect it, the Old Shaking Chest will appear as a reward at the end of the event.

To maximize your chances of success, it is important to prepare adequately. First, ensure that your character is well-equipped with weapons, armor, and accessories appropriate for your current progression tier. For example, if you are attempting the first tier, having a full set of Shadow or Crimson armor and a strong weapon like the Minishark or a magic staff will be beneficial. For the second tier, you should have Hallowed or Chlorophyte armor and weapons like the Megashark or the Daedalus Stormbow. For the third tier, you will need Beetle or Spectre armor and powerful weapons like the Terra Blade or the Razorblade Typhoon.

In addition to your equipment, it is crucial to prepare your arena. Building a flat platform with multiple layers can help you maneuver and avoid enemy attacks. Adding walls can block certain projectiles and provide cover. You can also place traps and sentries to assist in defending the Crystal. The Tavernkeep sells various sentry summoning items, such as the Ballista Rod and the Explosive Trap Rod, which can be very useful during the event.

During the event, focus on prioritizing high-threat enemies, such as the Dark Mages and the Betsy in the later tiers. These enemies can deal significant damage to the Crystal if left unchecked. Use your strongest weapons and abilities to take them down quickly. Keep an eye on the Crystal's health and be ready to repair it using the Defender Medals you earn during the event. Repairing the Crystal can be done by interacting with the Stand and spending Defender Medals.

One common mistake players make is underestimating the difficulty of the event, especially in the higher tiers. It is important to have a well-prepared character and arena to handle the increasing number and strength of enemies. Another mistake is not paying attention to the Crystal's health, which can lead to failure if it is destroyed. Always be ready to repair the Crystal when necessary.

Advanced techniques include using specific class setups to optimize your performance. For example, a Ranger class with the Megashark and Chlorophyte Bullets can deal consistent damage from a safe distance. A Mage class with the Spectre Armor and powerful spells like the Razorblade Typhoon can clear waves of enemies quickly. A Melee class with the Terra Blade and Beetle Armor can tank damage while dealing high melee damage. Summoners can use powerful minions like the Stardust Dragon to assist in defending the Crystal.

Resource requirements for the event include having enough Defender Medals to purchase the Eternia Crystal and Stand, as well as any additional sentry summoning items you may want to use. You will also need materials to build your arena, such as platforms, walls, and traps. Preparing potions like Ironskin, Regeneration, and Swiftness can give you an edge during the event.

In summary, the Old Shaking Chest appears as a reward for successfully defending the Eternia Crystal during the Old One's Army event. To achieve this, you need to purchase the Eternia Crystal and Stand from the Tavernkeep, build a suitable arena, and equip your character with strong weapons and armor. Focus on defending the Crystal, prioritize high-threat enemies, and be ready to repair the Crystal if needed. With proper preparation and strategy, you can successfully complete the event and obtain the Old Shaking Chest, which contains valuable rewards like the Sentry Summoning items and other unique loot.
