In order to save his Realm from the incoming hordes of adventurers, Oryx must create a horde of his own. With this purpose in mind he turns to Skuld, who has taken the souls of brave departed heroes and corrupted them to fight for the Mad God. For years, Skuld has been slowly building an army, and this Halloween he will finally be ready to release his creations into the world. Will you be ready to fend off legions of the undead? Or will you be the next to join their ranks? (Official Announcement)
The Halloween 2014 event during which a large amount of zombies with a HP of 2500(?) spawn, which can happen a few times per realm. The zombies spawn at a seemingly random location on the map - as sometimes they end up as far as the beach or as far into the realm as the Godlands. Watch out for Oryx threatening to send his ‘zombie horde’ to know when the horde is coming.
The drops from each zombie include all T11 Halloween reskin weapons, Candy Corn, and the Infected skin. The paladin demon skin is instead unlocked through the alchemist. The soulbound damage required to get loot is quite low, considering that even with a massive group of players attacking the same zombie you can quite often still get loot. The zombies that the Zombie Horde spawns are exactly the same as when a player with Cursed Amulet of Zombification dies.
