The Sep 1 official schedule notice targets Sep 7, 2026 at 22:00 PDT / Sep 8 at 14:00 KST / Sep 8 at 06:00 BST for the Plague Zone content update. It lists a new stage type, Corrosion recipe, level 90 items, about 20 new Unique Stats, new Rune content, a Skin System and a statistics menu. The current released patch remains v1.01.05 until a released update is verified.
What the Sep 1 schedule notice adds
| TIME ZONE | TARGET TIME | STATUS |

| PDT / San Francisco | Sep 7, 2026 at 22:00 | Target schedule |
| KST / Seoul | Sep 8, 2026 at 14:00 | Target schedule |

The notice uses “Plague Zone” for the new stage type, while the Aug 19 development note used “Plaguelands.” Atlas preserves both names in the historical record and will confirm the final in-game label after the content is live.
What the official Plaguelands announcement confirms
| PLANNED FEATURE | OFFICIAL DETAIL | WHAT IS NOT CONFIRMED |
|---|---|---|
| Plaguelands | A tougher stage type planned for Nightmare difficulty onward; entering consumes Corruption. | Exact release date, enemy values, rewards, drop rates and best route. |
| New items | Level 90 items plus about 20 kinds of new Unique Stats. | The complete item list, stat values, sources and balance. |
| New Runes | New Rune types and additional Runes for existing types. | Rune names, node values, costs, rankings and build recommendations. |
| Skin System | Character appearance changes; the dark-fantasy skins in preparation are described as free for existing players as service-issue compensation before becoming paid items. | Delivery timing, the full skin catalogue and details for future skins. |
How Plaguelands is described in the dev note
The post says Corruption accumulates in proportion to play time and can also come from corroding items in the Cube. While Corruption remains above zero, players can fight stronger Plaguelands enemies. Players choose a Plague Intensity; higher intensity means stronger monsters and better treasure chests, with multiple tiers that unlock in sequence after clearing lower tiers.
The note also mentions Corrupted Soulstones obtained in Plaguelands, which can be used to challenge Plagued Act Bosses. These are official feature descriptions, not a published farming formula or guaranteed reward table.
What this means for current guides
- Keep v1.01.05 as the live baseline. The dev note does not announce a new released version.
- Do not pre-rank the new content. No complete Rune values, item stats, drop rates or best builds were published.
- Recheck the patch desk when the update lands. Stage access, Corruption behavior, rewards and balance should be updated from the final notes or repeatable tests.
- Keep historical and planned content separate. The September timing is a development target, not a confirmed launch timestamp.
