Reverse: 1999 4.0.0 version overview
Official version info
Version 4.0.0 is named "Gatekeeper", updated 2026-09-24, with the official site's "current version" field showing 4.0.0. It is part of the 2026 Box Parade celebration, and the studio published a companion version-info hub.
The Dongzhi system arrives
The launch character Crossbow grows into the new form "Huntsman Witch Crossbow" this version, serving as the core damage of the "Dongzhi" system . A new form for an old character means veteran players with limited resources do not need to start over.
Reverse: 1999 4.0.0 Dongzhi progression priorities
Core first or supports first
Suggested order: Dongzhi core (Crossbow) to Insight 2, then generic supports (such as Sotheby), then a generic survival slot (such as Marzo, Enigma, or J) . Max the core's Insight tier first, then fill supports, because supports amplify the core and carry little value while the core is unfinished (trade-off reasoning).
Insight and Psychube material rhythm
Insight materials come from the matching element stages, and Psychube materials from Pneuma Analysis. Farm the core to its Insight 2 line first, then concentrate on Pneuma Analysis for Gluttony Footage and Insight materials .
Reverse: 1999 Artificial Somnambulism full stars: Shallow and Deep Dream
The difference between the two zones
Somnambulism splits into Shallow Dream and Deep Dream. Shallow Dream star rewards refresh every Monday at 05:00, and at 100 cumulative stars you can claim the full reward weekly; Deep Dream holds 36 cumulative stars with rewards claimable only once per device reset, which happens at 05:00 on the 1st and 16th of each month
The core idea for full stars
Shallow Dream floors 1 to 5 have low investment needs, while floors 6 to 10 want one absolute core at Insight 2 plus two secondary characters . Element advantage adds roughly 30% damage, so alternating characters beats a single fixed lineup.
Reverse: 1999 resource stage order
| Stage | Drops | Priority |
|---|---|---|
| Pneuma Analysis | Gluttony Footage, Insight mats, Psychubes | High |
| Mint Aesthetics | Sharpodonty (gold) | Medium |
| Dust Motion | Dust (XP) | Medium |
| Harvest Rite | Corn Baby, Corn Lady | Low |
Why Pneuma Analysis first
Pneuma Analysis supplies the core materials for Psychube upgrades and has two high-yield runs per day . Psychube upgrades raise overall power more than low-tier materials, so it goes first.
Filling gold and XP
Once the core's Insight and Psychubes are set, fill in Mint Aesthetics and Dust Motion for gold and XP. Harvest Rite is only worth farming when Wilderness buildings need upgrading, making it the lowest priority.
Reverse: 1999 4.0.0 resource plan
| Priority | Item | Why |
|---|---|---|
| High | Crossbow to Insight 2 | Dongzhi core |
| High | Pneuma Analysis for Psychubes | Biggest power gain |
| Medium | Generic supports | Amplify the core |
| Medium | Generic survival slot | Keeps runs forgiving |
| Low | A second team | Not needed yet |
How to order stamina
Order stamina as core Insight, then Pneuma Analysis, then gold and XP, then Wilderness buildings. The reasoning: core Insight and Psychubes decide which stages you can clear, while Wilderness buildings are a long-term investment (trade-off reasoning).
Reading the Dongzhi skill loop
Crossbow's Dongzhi form runs on a cast, recover, recast loop. Supports exist to fill the gaps between loops, so raise the core's Insight tier before filling supports (trade-off reasoning). When Psychube and Resonance levels lag, the loop visibly stutters; top up the Psychube before pushing raw levels.
When to upgrade Wilderness buildings
Wilderness buildings such as the Dust Clock Tower and Sharpodonty Market are long-term investments that steadily produce XP and gold. Upgrade them after the core's Insight and Psychubes are set, otherwise they eat the current patch's stamina (trade-off reasoning). Harvest Rite is only worth farming when a building needs ranking up, making it the lowest-priority resource stage.
Where the budget should stop
If the core's Insight 2 and Psychube line are still short this patch, stop chasing a second team and bank instead. Deep Dream resets at 05:00 on the 1st and 16th of each month , so partial progress resets anyway; a clean core clears more than a half-built pair.
Stamina order in practice
Run the order as a loop: Pneuma Analysis until the Psychube line is set, then Mint Aesthetics and Dust Motion to top up gold and XP, then Wilderness buildings last. Re-check Deep Dream after each monthly reset at 05:00 on the 1st and 16th, since both stages and rewards reset together.
What to do if the core is not ready
If Crossbow is still short of Insight 2, skip the second team entirely this patch and put every point of stamina into his Insight line. A half-built pair loses to a finished core on both Shallow and Deep Dream, and Deep Dream rewards reset anyway (trade-off reasoning).Detailed explanations can be found on Gghubs.

- Palworld v1.0.5 Worker Pals and Base Work Suitability: Single-Role vs Multi-Role, Star Ascension, and Pal Souls
In Palworld v1.0.5, base efficiency is not about catching the biggest Pal but about pushing Work Suitability to level 10. The 1.0 release raised the Work Suitability cap to 10 and cut the same-species Pals needed for a four-star from 116 down to 48. Long production lines want single-role Pals, short cycles want multi-role Pals, and that split saves the most base slots.
- Love and Deepspace "Ten Days With You" 19 Check-Ins and Autumn Portrait: Memory-Cultivation Rebate and October Planning
Love and Deepspace's "Ten Days With You" season 19 opened on 2026-09-28 05:00: ten days of check-ins grant the Memory Qin Che: Autumn Portrait. The check-in window closes on 2026-10-16 04:59. October also stacks the Memory Cultivation Rebate season 14 and the Meow Counter season 13, so spend stamina on the rebate event first rather than farming materials blindly.
- Honkai: Star Rail 4.6 Forgotten Hall Teams and Erosion Tunnel Relic Farming: Pearl's Elation Team and Star-Cloud Pets
In Honkai: Star Rail 4.6, Pearl is an Elation-path Ice character whose job is not a DPS slot but "survival plus tempo". Her ultimate advances allies and generates Elation resources, so both generalist teams this patch are built around an Elation resource loop, and the new relics should go to your main carry before a second team.
- Genshin Impact 7.1 Abyss Floor 12 Lineups: Visner's Wind Spread and Voyanisa's Hydro Core
In Genshin Impact 7.1, build Abyss Floor 12 around a split: send the Wind spread carry Visner to the first half to clear multi-target waves, and the banner Hydro unit Voyanisa to the second half for single-target burst. Both teams share the same generic supports, so you do not need to re-farm a full artifact set per chamber.

Wuthering Waves 3.7 adds three new Echo sets, and "Dream-Keeping Heart" is the endgame set for the Sentinel "Heart". Run it as a 5-piece with a Crit DMG 4-Cost main stat. Heart's endgame targets are 2,400+ ATK, 78% to 85% crit rate, 270% to 280% crit damage, and 130%+ Energy Regen, and the easiest Tower of Adversity clear is Heart with Suoming and Shorekeeper.
- Zenless Zone Zero 3.2 Claret Drive Disc and Team Guide: DEF-Scaling "Vanguard", W-Engine, and Shiyu Defense Lineups
In Zenless Zone Zero 3.2, Claret is the first "Vanguard" Agent and her damage is based on DEF. Once crit rate hits 100%, any overflow converts into an extra "sharp crit" check. So the build order is fixed: stack DEF, then balance crit, then crit damage. For Shiyu Defense, run her as the on-field carry with one Wind Break slot.

Palworld is currently on v1.0.5 (2026-09-15).

The breeding rules themselves did not change: an egg inherits from the combined passive pool of both parents, every Pal carries at most 4 passives, and the reliable way to hand a specific trait to a child is to have both parents carry it.
