Blizzard is updating Hallow’s End with an optional increased difficulty and all new curse mechanics for the Headless Horseman encounter! The updated dungeon event is now available for testing over the next two weeks on the Dragonflight Patch 10.1.7 PTR.
We previously speculated on these new “hard mode” mechanics, which curse players with up to four different debuffs, but rewards the Kickin’ With the Wick achievement and extra loot for surviving the encounter.
