KMS event · Ended · About these guides
At the end of Korean Challenger World season 4, protecting earned rewards and preparing a transfer mattered as much as another level. This article records that season's wrap-up process; its September 2026 transfer window has ended.
Characters needed an eligible World Leap to continue in a permanent world. Coins, shared storage, and Cash Shop storage did not simply follow them automatically, so preparation affected what could be kept.
Growth events and the final transfer window had different deadlines. The checklist below explains the steps for that Korean season; it is not an active GMS transfer opportunity.
KMS season-four closing dates
Character growth ended before September 17, 2026 maintenance. The second advance leap ended September 16 at 11:59 p.m. KST. The final leap ran from after September 17 maintenance through September 30 at 11:59 p.m. KST. Those windows are now historical.
Major events such as Challenger Pass and Item Burning PLUS growth had earlier cutoffs than the final leap. The source recommended treating September 16 as the practical preparation deadline. Its original link below points to an earlier test notice: the source's Korean Test World announcement. For the final season-four schedule and restrictions, use the live June notice linked in the regional notes at the end of this article.
| Activity | Korean closing time |
|---|---|
| Main growth events | September 16, 2026, 11:59 p.m. KST |
| Second advance leap | September 16, 2026, 11:59 p.m. KST |
| Challenger character growth | Before September 17 maintenance |
| Final World Leap | After September 17 maintenance through September 30, 11:59 p.m. KST |
Claim Challenger Pass rewards before the deadline
A completed pass level did not necessarily mean its reward had already entered the inventory. The source's first check was the actual claim button and reward state.
Players with the paid tier also needed to check Premium claims. Before the deadline, remaining daily and weekly missions could be compared with the points needed for the next useful milestone. Expired opportunities cannot now be recovered by following this checklist.
The review order was:
- Check the current Challenger Pass level.
- Review unclaimed free and Premium rewards.
- Count only remaining eligible missions.
- Read voucher and selector expiration.
- Choose which character would use each reward.
Some item timers begin when claimed. Read the specific tooltip before assuming every reward shares the pass's closing time.
Finish Item Burning PLUS growth before leaving
An early leap to a regular world stopped further Challenger equipment growth. Players still working on those missions needed to check the sequence before moving.
Review the current stage, next requirements, and qualifying boss missions. Some later missions required solo clears, making equipment, nodes, and practice relevant before departure.
Use practice mode only where that particular mission permits it. Likewise, confirm whether a later-stage boss could be credited before completing the preceding stage; those exceptions do not apply to every event mission.
The intended sequence was:
Check missions → clear qualifying bosses → grow equipment → claim rewards → World Leap
Leaving first was not a reversible way to continue unfinished growth. The separate equipment-use expiration remained November 18, 2026 at 11:59 p.m. KST; the end of growth did not immediately delete the gear.
Use Challenger coins under the season's rules
Challenger-only coins did not automatically become currency in the destination world. Review useful shop exchanges before leaving, subject to the actual shop and item deadlines.
The source's categories to inspect included:
- Sol Erda and Sol Erda Fragments
- Karma black rebirth flames (Korean item category)
- Karma master-crafting cubes (Korean item category)
- Bonus Potential resources
- Symbol selectors
- Experience Nodestones
- Trait growth items
- Monster Park-related items
This is a review list, not an instruction to buy everything or a GMS product catalog. Prioritize the character continuing in the permanent world, and use event-world-only items before their specific deadline if eligible.
Check restricted cubes and Star Force coupons for labels stating that they work only in Challenger or cannot World Leap. A transferable-looking box can still have restricted contents.
Review shared storage and Cash Shop storage
Eligible inventory items could move with the character, but shared storage and Cash Shop storage did not move automatically. Item-specific restrictions still applied even after withdrawing something.
Place the permitted items you intended to keep into the transferring character's inventory.
Shared-storage review list
- Mesos
- Spell Traces
- Nodestones
- Sol Erda Fragments
- Rebirth flames
- Enhancement scrolls
- Tradeable equipment
- Event reward boxes
Cash Shop storage review list
- Pets and pet equipment
- Cosmetics
- Items moved through Cash Inventory Transfer
- Hair and face coupons
- Cash throwing stars and weapons
The final Korean notice excludes items left in storage, Cash Shop storage, or the Auction House from automatic transfer. Registered custom backgrounds also need their own handling; check whether an eligible extraction is possible rather than assuming the list itself moves.
Resolve Auction House and official Meso Market transactions
Review pending listings, unclaimed sale proceeds, and purchased items before leaving a trade-enabled world.
The source's transaction checklist includes:
- Active sale listings
- Unclaimed completed-sale mesos
- Unclaimed purchased items
- Watchlist and pending-order states, where applicable
- Open official Meso Market trades
- Unclaimed Maple Points or mesos from those trades
An open Meso Market trade can restrict a leap. Complete or cancel applicable transactions and collect eligible proceeds before attempting the transfer. These are Korean official-market checks, not outside cash-trading instructions.
Choose up to five characters for the season
The Korean season's five-character total includes both advance and final leaps. Using all five earlier left no extra slot in the final window.
A player saving the main for last needed to avoid transferring five other characters first.
Possible priorities included:
- The main developed with Hyper Burning
- The character holding Item Burning equipment
- Other characters developed to a useful level
- Classes with useful Link Skills
- Characters contributing useful Legion bonuses
The season's entry level was at least 101; Zero also needed Chapter 2 completed. These conditions describe that Korean season, not every GMS event world.
Choose the destination before the first transfer
Eligible destination groups depended on the starting Challenger world.
Challenger, Challenger 2, and Challenger 3 could move to the listed Korean regular worlds: Scania, Bera, Luna, Zenith, Croa, Union, Elysium, Enosis, Red, Aurora, Arcane, and Nova. Challenger 4 could move to Eos or Helios. These are KMS routes, including world names that can resemble GMS names.
The first origin-and-destination selection could not be changed later. Consider the intended main's home, resources, Legion development, friends, and guild before moving an alt first.
Check boss and weekly tasks before leaving
Event-world bonuses ended on transfer. A fight cleared comfortably there could take longer or become difficult without those bonuses in the destination world.
Before the historical cutoff, the source recommended reviewing:
- Boss missions required for Item Burning
- Challenger-only seasonal bosses
- Weekly boss crystal claims
- Epic Dungeon and applicable bonus rewards
- Monster Park and Extreme Monster Park
- Weekly pass missions
- Event attendance and cumulative rewards
Check reward-sharing and entry limits before assuming a transfer grants another clear or reward. Guild membership also did not carry over as a substitute for joining a guild in the destination world.
Settings to rebuild after arrival
The destination world's systems replace the Challenger-only environment. If displayed power falls, review missing settings and expired bonuses before assuming equipment was lost.
Link Skills
Apply the available destination-world links to the main, with separate farming and bossing presets where useful.
Legion board
Arrange the blocks for the required Critical Damage, Boss Damage, Ignore Enemy Defense, or normal-monster damage.
Legion Artifact
Confirm the destination world's Artifact effects are applied. They may replace some, but not necessarily all, of the lost event bonuses.
Equipment and Oz rings
Prepare permanent-world rings where the Challenger versions cannot transfer, and plan replacements before temporary gear expires. The Item Burning growth deadline and usage deadline are separate.
Save the presets again
Review Link Skills, Legion, Hyper Stats, Inner Ability, equipment, and pet buffs for farming and bossing. Test the actual setup instead of trusting an old preset name.
The season-four final checklist
For this ended Korean event, the original preparation list was:
- Claim eligible Challenger Pass rewards.
- Finish Item Burning PLUS growth missions.
- Claim attendance and cumulative rewards.
- Exchange useful Challenger coins within the allowed window.
- Use eligible event-only cubes and enhancement coupons.
- Withdraw transferable shared-storage items into inventory.
- Review and withdraw eligible Cash Shop storage items.
- Resolve Auction House items and proceeds.
- Complete or cancel official Meso Market trades as required.
- Review custom backgrounds and expiring items.
- Finish eligible weekly and Epic Dungeon tasks without assuming duplicate rewards.
- Choose the season's five transferring characters.
- Confirm the destination and slot rules.
- Rebuild Links and Legion after arrival. For a later season or GMS event, start again with that event's own official notice rather than reusing these expired dates.
