The Pumpkin Moon is an endgame Halloween-themed event summoned with the Pumpkin Moon Medallion at night, and ends at dawn (4:30AM). During the event, unique and highly difficult enemies spawn at high rates and attack the player. It is similar to the Frost Moon event, though slightly less difficult, and is currently the second most difficult event in the game (the first being the Frost Moon). Visually, the moon turns into a jack-o-lantern, though remaining in its current phase. Unique music also plays.
The entire Pumpkin Moon event consists of 15 waves, which progress as you reach certain kill scores (though kill scores are not displayed to the player). Each killed enemy increases the kill score by a differing amount. After a wave's required score is met, the next wave begins, and the kill score is reset to 0. Chat messages will indicate when the wave has advanced, and which wave has been achieved. See the table below (Waves) for the points awarded for each enemy and the score required for each wave.
The Pumpkin Moon Medallion that summons the Pumpkin Moon requires materials only available in Hardmode worlds where the player has already defeated Plantera. As such, it is intended to present a challenge even to players with the best possible equipment. However, it can be triggered on a pre-Hardmode world. In the final waves, multiple boss-level enemies are fought at once.
Pumpkin Moon enemies drop powerful weapons and accessories. There are also pet and vanity items. Most drop with extreme rarity, and even players who manage to complete the event will find they need to do so several times before obtaining them. Drop chances for Boss-dropped items increase the later the wave in which they spawn. In the final wave, the Mourning Wood and Pumpking are both guaranteed to drop their respective Trophies.

- Water Candles, Battle Potions and Calming Potions have no effect during the invasion.
- If the player is killed during the event, the event is not cancelled. The player will keep re-spawning and can continue fighting its enemies as the event continues until dawn. In single-player games, exiting the world and reloading it will cancel the event.
- Pumpking is the only boss in the event that flies consistently through blocks and cannot be confined. It behaves similarly to Skeletron Prime, and has a similar size.
- The Pumpkin Moon does not stack with the Blood Moon. Summoning the Pumpkin Moon will cancel the Blood Moon if it is active.
- Spawn rates for areas where Pumpkin Moon enemies cannot spawn are also increased. For example, there will spawn lots of Sharks and Crabs in the Ocean, allowing the player to farm for Pirate Maps.
- The event can be triggered in pre-Hardmode worlds if its summoning item is brought there.
- Most Pumpkin Moon enemies are susceptible to the Ichor Debuff, which makes a Flask of Ichor or the Golden Shower spell very effective.
- Create an Arena with several Traps to deal with the smaller enemies while you focus on the Pumpking, such as the one detailed in the video to the right.
- Kill the enemies as soon as they spawn, to ensure that more enemies can spawn continuously, in order to increase the chances of achieving later waves. The arena should have predictable spawning zones and no caves where enemies can become trapped. Extra spawning layers can be created with a height of three blocks to take advantage of the anomaly of the Spiky Ball Trap that shoots up if there are two blocks below it. The spawning layers should have enough distance from each other so that the Mourning Wood can spawn between them, and the Traps should all be connected together by the same wire and be activated by a Timer or by using several Yellow Pressure Plate, which ignore the player. Where the enemies spawn relative to the player depends on the game resolution. If playing in 800x600 they will spawn the closest to the player. After a night, if the spawning pads are long enough, there should be seen clusters of loot indicating where they spawn. The arena can be tested by summoning a Pirate Invasion-the invasion should be defeated in record time and a minimal number of enemies should reach the player. While using this strategy during the Pumpkin Moon, the only serious threat will be the Pumpking. If all of these suggestions are followed, melee character with Vampire Knives can beat this event.
- Using stynger may be the best choice to the ranged weapon users, as it is one of the best weapons if dealing with multiple enemies at once. Against the Headless Horseman, Mourning Wood or Pumpking, however, the Tsunami or the Chlorophyte Shotbow might be a better choice since these can shoot multiple arrows at once.
- The Razorpine is extremely effective against enemies and bosses alike, since it is easily able to cause thousands of points of damage in a matter of seconds.
