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 and the infected skin at present. The paladin demon skin is instead unlocked through the alchemist. Other class skins do not drop from the zombie horde currently, and it is unsure whether or not they will drop from the zombie horde or be given from the alchemist - if at all.
The soulbound damage required to get loot seems like it may be 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.
