Season 4: Moon Surge Rhapsody

Overview

Season 4 of Roco Kingdom: World is titled Moon Surge Rhapsody (月涌狂想). It went live on September 10, 2026 at 04:00 China time and runs to November 5, 2026 at 04:00. The season closes out the fairy-tale framing of Season 3: Lead-Type Dream and moves the story to the lunar surface, which the official framing describes as a place the Rocos have never set foot on, reached under a meteor shower and tied to an old legend about wolves and the moon.

The season hall is called the Moon Surface (月面). It is where season rewards are exchanged and where the season commission chapters are tracked. Season spaces this time carry a low-gravity float effect, so movement inside them behaves differently from the open world.

Season Window

Launch Maintenance and Compensation

Unlike the two hot updates that preceded it, the season launch took the servers down. Maintenance ran from 00:00 to 10:00 on September 10, 2026 with login blocked throughout, and the client was swapped rather than patched in place. The build after the update is version 1.111.

A companion login event, Kingdom Promise (王国之约), runs the full length of the season from September 10 to November 5. It unlocks once the player has finished the main-story step that has them speak to Iris during New Student Life, and seven cumulative login days award a four-pointed-star chromatic egg, a heart chromatic egg, a cube chromatic egg, a King Ball and a Prism Ball.

Season Structure and Rewards

Completing chapter one of the season homework grants a Cursed Wolf Spirit egg. It hatches at flawless quality with a player-chosen nature and a player-chosen individual-value tendency, and carries the Fearless speciality, so the season legendary is obtainable without any purchase.

New cosmetics include the Wolf Child Hat fashion part, and the season toys convert to permanent items once the season closes.

Silver Moon Wolf King

The season legendary is the Silver Moon Wolf King (银月狼王), the final form of the Cursed Wolf Spirit (诅咒狼灵) family. The published line runs Cursed Wolf Spirit into Crescent Moon Wolf Spirit (新月狼灵) and then into Silver Moon Wolf King. It is a two-seat mount, so a second player can ride along.

A personal name and an element typing for the legendary circulated in community write-ups before launch. Neither appears in any official post, so neither is recorded here. English names for the line are literal translations of the Chinese; no official English rendering exists for them, because the Chinese client has no English text and the six official English names published so far cover a different set of creatures. See Spirits for how naming is handled across this wiki.

Starfall Streaming Light

Moon Surge Rhapsody introduces Starfall Streaming Light (星陨流光), the season's special encounter. Capturing spirits in an unbroken run gives a chance to trigger a meteor visit, and the meteor brings a season spirit with it. It replaces the season-encounter mechanics used in earlier seasons rather than running alongside them, and it pairs with a new item, the Moon Surge Prism Ball (月涌棱镜球).

Season Encounter Spirits

Eight spirits were named in the official pre-season dex posts as the ones reachable through the season encounter. Chinese names are the authoritative identifiers; the English column is a literal rendering, not an official name.

One community round-up printed 智慧章脑 and 测风蝉 in place of 章脑丸 and 量风碗. That page carries a self-declared notice that it was machine generated, and the official post is the authority, so the names in the table above are the ones used on this wiki.

Moon Surge Pass

The season pass is the Moon Surge Pass (月涌通行证). Two theme spirits are attached to it: Holy Kaibu Rice Dragon (圣凯布米龙), a Fire and Bug type, and Moon Envoy Luna (月使鹭纳), an Ice and Wing type. Both are pass-limited for the season in the same way earlier seasons handled their pass spirits, described on Season Pass and Monetization.

Season Emotes and Toys

Four season emotes shipped with the update, each at two levels: Call (呼唤), Sneak (偷偷摸摸), Surprise (惊喜) and Head Pat (摸摸头). They are unlocked by progressing the season commission chapters and then exchanged at the Moon Surface season hall using Wish Stars. One of them is a two-player action. Season toys convert to permanent items when the season ends and stay exchangeable with Wish Stars afterwards.

Season 4 Spirit Data

The official dex sheets published between September 2 and September 10, 2026 carry per-entity data for every new family. Stat blocks are given for the final stage only; earlier stages publish size and flavour text but no stat line. The stat order used below matches the sheets: HP, Physical Attack, Magic Attack, Physical Defence, Magic Defence, Speed.

Cursed Wolf Spirit Family (诅咒狼灵家族)

The season legendary line. All three stages are Ghost and Illusion type, and the last two are rideable.

Its species trait is Engraved on the Moon (铭记于月亮): it gains the trait of any spirit it defeats, and loses 5 percent of its own health after every attack. Its published skills are Soul Parting (离魂术, steals 2 energy from the opponent then withdraws), Shadow Sweep (掠影, physical damage, and steals 3 energy if either side used a Fire skill on the previous turn), Recombine (重组, the next attack deals an extra 100 percent as Illusion damage, raised to 300 percent against a defending target) and Lunar Eclipse (月蚀, physical damage costing 3 less energy if the target is below half health).

Pass Families

Both Moon Surge Pass lines follow the same design: a trait that doubles one of the family's two element types when the other element was used on the previous turn.

圣凯布米龙 evolves through 热团团 and 焰米龙, with chromatic forms shown for all three stages. 月使鹭纳 evolves through 新月鹭 and 月辉鹭. Their published skill sets are Warm Sun, Starfire, Swarm Wisdom and Flame Cut for the Fire line, and Fleeting Glimpse, Moonshadow Weave, Snowball Fight and Wing Shelter for the Ice line.

Season Encounter Families

All eight season encounter spirits reachable through Starfall Streaming Light. Two of them, Star Eyes and Unfinished Bug, are single-stage and have no evolution.

Star Eyes carries the season's clearest link to the theme. Its dex flavour describes it as a meteorite that fell onto the Continent of Carosia in ancient times and was brought to life by magic-rich soil, and its skills read as an observation set: Gaze at the Night Sky raises its own Magic Attack and Magic Defence by 70 percent, Observer Effect withdraws it and brings the replacement in under a Moon Meteor state, Meditation cuts incoming damage by 80 percent and puts 2 layers of Starfall Imprint on an attacker, and Derangement deals magic damage and adds 3 layers against a target using a status move.

A naming note worth recording. Community round-ups printed 测风蝉 and 智辉章脑 where the official announcement post printed 量风碗 and 章脑丸. Both sets are correct: the official post named the base forms and the round-ups named the final forms of the same two families. This is a stage difference, not a contradiction.

Weekly Family Sheets

Three further family sheets were published inside the season window for the weekend mass-spawn events.

The Mole family has both a water-storing form and a dry-season form, and the weekend event confirmed chromatic versions of both. The Little Spirit Mushroom family shifts typing as it evolves, starting as pure Ghost and gaining Grass from its second stage.

New Systems and Economy Rework

Season 4 is a systems update as much as a content update. The largest addition is the Sub-Academy System, which sorts players into one of four houses and runs on a two-season semester clock.

Spectral Crystal and Season Token Rework

Crystal and token sources were rebalanced rather than simply increased. Several old sources stopped producing crystals and now produce season tokens instead, and the crystal output was concentrated into the new credit tasks.

The published season totals are 14,500 Spectral Crystal, up from 12,720, and 26,720 season tokens, up from 23,920. One transition rule applied: the Starlight Showdown running from September 7 to September 14 still paid Spectral Crystal, and only the following cycle onward stopped.

Imprint Challenge Changes

• Flower Seed encounters can now spawn chromatic variants, and the magic handbook shows the chromatic marker without entering.

• Destined Flower Seeds, Rare Beast Flower Seeds and Legendary Spirit Battles gained a Challenge Again button.

• A crafting recipe for the current season's commemorative ball opened at Magic Level 50 and the Spirit Scholar-of-Wide-Learning rank, using Contract Imprints at the alchemy cauldron.

• Spirit Leader fights gained a chromatic egg drop that hatches a leader-bloodline spirit with a chromatic appearance and the Remarkable talent.

• Spirit Leader respawn after claiming rewards dropped from five minutes to five seconds, and the post-defeat status label changed from Reviving to Resting.

Reward Recovery

Missed monthly-card daily rewards now auto-store as Recovered Resources for up to three days and are claimed from the season assistant. Recovery only accrues while the card is active, and rewards missed before the September 10 update cannot be recorded retroactively. Missed heat medals can be recovered during the season sprint, with the recovery count tied to the number of days missed.

Time Rewind

Time Rewind (时光回溯) ran from the September 10 update to September 24, 2026 at 04:00. Any spirit that has had raising resources invested in it, whether feeding, growth, awakening or bloodline modification, could be returned to the state it was first met in. Nicknames and intimacy were kept.

Each player received 36 rewinds, valid only inside that window, with leftovers cleared at the end. A spirit could be rewound only once, the rewind could not be undone, and rewound spirits were excluded from bulk release until the counter ran out. The window also allowed re-evolving a spirit down a different branch afterwards, which is the only sanctioned way to change a branch choice.

Collegiate Invitational

The first Collegiate Invitational (高校邀请赛) opened alongside the season on September 10, 2026. Students verify their school, then contribute to two separate boards.

The competitive format it feeds from is covered on PvP and Shining Contest.

Season 1 Content Returning

Season 4 brought a block of Season 1 content back, some of it permanently. The Memory Shop (记忆商店) and the expanded Rare Beast Flower Seed roster became permanent from the September 10 update.

A second wave becomes permanent from October 1, 2026 at 04:00: the Legendary Spirit Battle against Dragon Breath Parasus, the Season 1 chromatic collection task, and the Dream-Weaving Prism Ball. Two things in that wave are temporary and are removed when Season 4 ends: the Dragon Breath Parasus event and its rewards, and the route that lets the season encounter produce Season 1 adventure spirits.

The Memory Shop prices its stock in Memory Tokens. Season 1 adventure spirit fruits cost 200 each, covering Bethel, Twin-Light Fish, Light-Devouring Buzz, Ash Debris Worm, Hollow Skull, Crescent Snow Bear, Pink Star Jr. and 粉粉星. The Season 1 free outfit costs 800, its bag charm 400, and the Season 1 commemorative ball costs 1. With the season contract voucher active, pass spirit fruits cost 2,000 each, the season staff 1,600, outfits 800 a set, namecards 400, and alchemy recipes 400.

Cosmic Pioneer Monthly Pack

The Pica Monthly bundle for the season opening is Cosmic Pioneer (宇宙拓荒者), on sale from the completion of the September 10 update to September 25, 2026 at 04:00. The outfit carries its own magic effects and unlocks dedicated interactions with three specific spirits: Silent Bone Dragon (寂灭骨龙), Star Eyes (星星眼) and Wise Radiance Chapter Brain (智辉章脑). The themed staff changes Star Magic so the mechanical satellite at the staff tip gathers energy first, then bursts into meteor fragments.

Two shop changes landed with it. The Why Use A Magic Broom As A Paintbrush (怎么可以用魔法扫帚当画笔) pack was delisted once the September 10 update completed, and the Secret Infiltration Plan (秘密潜入计划) outfit moved into the random shop. A standing rule was published at the same time: Pica Monthly sets and all their loose pieces enter the random shop 42 days after they are delisted, while themed staffs, themed bag charms and themed namecards never do. See Pica Monthly.

Economy Changes

Spectral Crystal (分光水晶) output was raised across the season, but stamina no longer produces crystals, so the routes that used to farm them through stamina spending were closed. An Academy Monthly Supply (学院月度补给) was added, and pass experience gained an after-the-fact claim path for players who miss it. Currency handling is covered on Resources and Currency.

Season Calendar

Dates below are drawn from official announcements. Times are China server time and end timestamps fall at 04:00.

The Cocoa Harvest Festival hands out 480 free Cocoa Fruit Balls, and each one is stated to guarantee a Starfall Streaming Light encounter. The Legendary Spirit Battle on October 1 features Dragon Breath Parasus.

Book Donation Campaign

Alongside the season the team ran a reading campaign built on the in-game Spirit Survey Team missions. Working with a charitable foundation and a parental-guardianship platform, the campaign donated 11,990 animal science books to 22 rural primary and secondary schools in Tibetan communities across Qinghai, Sichuan, Tibet and Yunnan, framed as a real-world counterpart to the in-game observation notes.
