===Pumpkin Moon===
A Halloween-y event that can only be initiated by use of the Pumpkin Moon Medallion, an item constructed from Pumpkins (which only grow around Halloween initially), Ectoplasm, and Hallowed Bars. The Pumpkin Moon lasts one night, and consists of up to 15 ball-crushingly brutal enemy waves that culminate in not one but two consecutive boss fights, against the Mourning Wood (yes, really), and the almighty Pumpking. You will not only have to focus on staying alive, but also on micromanaging the rate at which you kill enemies, so as to ensure that the event progresses to waves 14 and 15 before you kill the bosses; killing them any earlier drastically reduces the odds of them dropping some of the best loot in the game. So yeah, not only is it incredibly tough, it's finicky bullshit as well. Fantastic!

If you get to wave 15 (or the final wave, 20, in older versions), the normally season-locked Halloween content will become available for an entire ingame day.
