How do I trigger a Pumpkin Moon event in Terraria?

To trigger a Pumpkin Moon event in Terraria, you need to craft and use a Pumpkin Moon Medallion. This event is a challenging wave-based invasion that occurs at night and is designed for mid-to-late-game players. The Pumpkin Moon event is one of the most rewarding events in the game, offering unique loot and high-tier crafting materials. Below is a detailed guide on how to trigger and prepare for the Pumpkin Moon event.

The Pumpkin Moon Medallion is crafted using specific materials. You will need 30 Pumpkins, 5 Ectoplasm, and 10 Hallowed Bars. Pumpkins can be grown from Pumpkin Seeds, which are obtained by cutting grass during the Halloween season or by purchasing them from the Dryad during that time. Ectoplasm is dropped by Dungeon Spirits, which spawn in the Dungeon after defeating Plantera. Hallowed Bars are crafted from Hallowed Ore, which is mined in the Underground Hallow biome after defeating the Mechanical Bosses (The Twins, The Destroyer, and Skeletron Prime). Once you have gathered these materials, you can craft the Pumpkin Moon Medallion at a Mythril or Orichalcum Anvil.

To start the event, use the Pumpkin Moon Medallion at night. The event will begin immediately, and the night will not progress until the event ends or you die. The Pumpkin Moon event consists of 15 waves, with each wave becoming progressively more difficult. The goal is to survive and defeat as many enemies as possible to reach higher waves, which yield better rewards. The event ends at dawn (4:30 AM in-game time) or if you die.

Preparation is key to surviving the Pumpkin Moon event. First, ensure you have a strong arena set up. A flat, open area with platforms for mobility is ideal. Place campfires, heart lanterns, and honey pools for health regeneration. Star in a Bottle or similar items can help with mana regeneration if you are using magic-based weapons. Traps and lava pits can also be useful for dealing with weaker enemies, but they are less effective against the stronger bosses that appear in later waves.

For combat, you will need powerful weapons and armor. The best armor sets for this event depend on your chosen class. Melee players should aim for Beetle Armor, ranged players for Shroomite Armor, magic users for Spectre Armor, and summoners for Tiki Armor or Spooky Armor. Weapons should be high-tier and suited to your class. For example, melee players might use the Terra Blade or Vampire Knives, ranged players could use the Chain Gun or Tsunami, magic users might rely on the Razorpine or Razorblade Typhoon, and summoners could use the Tempest Staff or Xeno Staff.

Accessories should focus on increasing damage, defense, and mobility. Wings, such as Fishron Wings or Betsy's Wings, are essential for dodging attacks. Damage-boosting accessories like the Celestial Shell, Avenger Emblem, or Destroyer Emblem are highly recommended. The Ankh Shield provides immunity to many debuffs, which is crucial for surviving the event.

One common mistake is underestimating the difficulty of the Pumpkin Moon event. Even with strong gear, the later waves can be overwhelming if you are not prepared. Make sure to stock up on healing potions, such as Greater Healing Potions, and buff potions like Ironskin, Regeneration, and Swiftness. Ammo and mana potions should also be readily available if you are using ranged or magic weapons.

Advanced techniques include optimizing your arena with teleporters to quickly move around and avoid enemy attacks. Using a minecart track with bumpers can also help you maintain speed and avoid damage. Additionally, summoning minions or sentries can provide extra damage output, especially for summoners.

Resource management is crucial during the event. Focus on defeating the stronger enemies first, as they drop more points and better loot. The Mourning Wood and Pumpking are the primary bosses in this event, and defeating them quickly will help you progress through the waves faster. Keep an eye on your health and mana, and retreat to your arena's safe zones if necessary.

In summary, triggering the Pumpkin Moon event requires crafting a Pumpkin Moon Medallion and using it at night. Preparation involves building a strong arena, equipping high-tier gear, and stocking up on potions. Combat strategies should focus on maximizing damage output and mobility while managing resources effectively. By following these steps and avoiding common mistakes, you can successfully complete the Pumpkin Moon event and reap its valuable rewards.
