ZenlessZoneZero Event: Whitering Garden-Core
3The Withering Garden is one of the Zones within Hollow Zero. It is one of the most dangerous areas within the Hollow and is the home of the Disaster-class Ethereal Nineveh, the Zone's final boss.
To gain access to the Withering Garden, players must have reached an Inter-Knot Level of 45. Players must also clear the Core-difficulty levels of the previous three Hollow Zero Zones, i.e. the Old Capital Metro, Construction Ruins, and the Abandoned Skyscraper.
Unlike previous Zones which have a distinct floor mechanic unique to them, the Withering Garden draw on the floor mechanics of all the previous Zones to randomize which mechanics it will use for its floors, adding another layer of randomness to the Withering Garden's layout.
Asides from the previous floor mechanics, Hollow Zero also has its own unique potential floor layout: this floor type is based off the Construction Ruin's disappearing tiles mechanic, but with vertical movement being restricted to one-way rails and springs, both which prevent vertical backtracking.
Players do not immediately fight the final boss upon reaching the end of the third floor, and instead they are taken directly to a third Frontline Outpost with which they can acquire last-minute healing and supplies; notably, this Frontline Outpost does not have the S-Rank gate for additional supplies, nor a Bank Zero, though this outpost will always have a Bangboo Merchant to buy last-minute Resonia and catalysts from. Exiting this area will take players to a short corridor leading to the final boss fight at the end.
