KMS→GMS Roadmap

MapleStory GMS is on v247 Assemble. KMS is on 1.2.412 Crown. The list below is the truth state at this snapshot — what shipped, what's already in KMS but not GMS yet, and our best window for each GMS rollout. Use the prep hints to avoid wasting Sol Erda, NX, and cube charges on soon-to-be-power-creeped systems.

What's queued for GMS (8 items)

Forecast

KMS Crown — Kinesis Remaster → GMS v248

High confidence 2026-07-15 → 2026-09-15
  • Kinesis full remaster Class Reform

    GMS Kinesis mains: kit redesign coming; Psychic Point system overhauled.

    ↳ Prep: Stop pushing HEXA Cores on Kinesis until remaster lands — old efficiencies will reset.

  • Cash Inventory unification Cash ShopQoL

    Officially confirmed for GMS Summer 2026 — cross-character NX inventory access.

    ↳ Prep: Don't buy duplicate NX on mules; one purchase will cover the account.

  • Quality-of-life inventory revamp QoL

    Auto-sort and batch mule transfer.

Resource prep
  • · Hold Sol Erda Fragments — class reforms always reset optimal Mastery order.
  • · Stop buying Cash Inventory NX on multiple mules; unification removes the need.
  • · Save Cubic Blades / Red Cubes — class reform shuffles BiS lines for Kinesis.
Forecast

KMS Crown — Challenge World → GMS v249

Medium confidence 2026-09-15 → 2026-11-30
  • Challenge World "Sea" rotation RegionSystem

    Time-limited challenge world with separate progression and shared cosmetic rewards.

    ↳ Prep: Reserve a slot — Challenge World runs typically take 60–90 days.

  • Tier 2 Sacred symbols SymbolSystem

    New symbol upgrade tier — caps at Lv 11, requires First Adversary mats.

    ↳ Prep: Stockpile First Adversary entries — symbol push competes for the same lockout.

Resource prep
  • · Save symbol selectors and exchange coupons for the new Sacred tier.
  • · Plan a Challenge World main — different from your bossing main is fine.
  • · First Adversary clears feed both Sacred upgrade and Mastery — prioritize entries.
Forecast

KMS Echoes (provisional) → GMS v250

Low confidence 2026-12-15 → 2027-02-28
  • Class balance — KMS spring sweep Class Reform

    Major DPM rebalance pass historically lands every 12–14 months. Expect post-Assemble Mastery efficiency tuning.

    ↳ Prep: Don't pre-cap HEXA Stats with %class-specific lines on a class likely to get reworked (Wind Archer, Phantom, Battle Mage are next on KMS notes).

  • New endgame boss tier BossSystem

    KMS typically introduces a new endgame boss in spring updates. First Adversary follow-up rumored.

  • Hexa Mastery Lv 30 → 35 cap raise (rumored) HexaSystem

    Datamine hints suggest cap raise on Mastery slots — bigger fragment sink, bigger payoff.

    ↳ Prep: Hold Sol Erda Daily clears active for the cap raise window.

Resource prep
  • · Defer non-essential cube tapping until KMS spring rebalance is announced.
  • · Cycle Sol Erda Daily on every funded mule; cap raise uses old fragments at full value.
  • · Watch Orange Mushroom for rebalance leak — typical landing window is 6 weeks before patch.

Methodology

  • KMS/GMS patches — verified from Nexon KR posts, Maplestory.nexon.net patch notes, Orange Mushroom's blog, and community changelog threads.
  • Forecast windows — derived from observed cadence (~6-month KMS→GMS gap by mid-2026). Confidence is downgraded when KMS cadence shifted or when GMS roadmap commentary is missing.
  • Prep hints — opinionated. They flag resources that historically changed value when a system landed (Sol Erda Fragments before HEXA reform, cube charges before potential changes, NX before Cash Inventory unification).
  • Limitations — GMS occasionally compresses or skips KMS content (Hyper Burning order shifts, KMS-only events). Where windows are uncertain we mark Low confidence.
