New zones that don't exist traditionally
The datamine surfaces 78 named maps that have no traditional MapleStory-GMS wzId (the identifier maplestory.io uses to serve traditional MapleStory assets). These are the CoT 2 exclusives, broken down by region:
Forgotten Hollow (Victoria Island) - 40+ new maps
The biggest single addition: a whole new region below Victoria Island with its own NPC cast (Arthur, Bianca, Raymond, Oak, Flint, Roxy, Scarlett, Weston, Silas Irons, Luma, Zelya), its own mob composition, and its own quest chains. Includes:
- Forgotten Hollow proper, Marr's Forest, Niora Hospital, and multiple "Forgotten Entrance" corridors linking back to Victoria.
- Perilous Descent I-III, Bygone Days, The Faded Canopy, Decayed Tunnel I-III, and The Valley of Death - dungeon-style progression maps.
- Fully Bloomed Bluebell and Bluebell Bud as NPCs (yes, the flowers are characters), tied into an early Forgotten Hollow quest line.
Physical Fitness Test - the new event JQ system
17 CoT 2-only maps make up an entire jump-quest event system with difficulty tiers (Easy, Normal, and three numbered Levels). Includes a Waiting Room, per-level rooms ("Up and Up", "Coconut Season"), and Bianca as the gating NPC. This looks like Nexon's take on the classic OMOK-style event rotation, permanent instead of seasonal.
Henesys Town Hall + civic buildings
The Citizenship system introduced a physical Town Hall in Henesys (and presumably Kerning City) that houses citizenship registration, contribution turn-ins, and shop rotations. This building doesn't exist traditionally at all - see the Citizenship guide for how the whole system works.
Other structural additions
- Guild Head Quarters <Hall of Fame> in Orbis - dedicated guild-showcase map, brand new.
- Orbis Ticketing Booth - reworked ticketing interface for the ship travel network.
- Reworked Maple Island entry maps - "Mushroom Town - West Entrance", "East Entrance to Mushroom Town", "A Split Road", "Snail Hunting Ground I" all show up as CoT 2-only renames/expansions of the tutorial flow.
- Free Market instances 1-N - the FM channel splits work differently in CoT 2 (details TBD until we're on live servers to see the actual queue behavior).
Two brand-new systems layered on top
Citizenship (Henesys or Kerning City)
Not a traditional MapleStory system at all. At Lv 12, you pick a town allegiance, earn contribution via daily quests and events, and climb 10 grades to unlock town-exclusive gear, chairs, and cosmetic access. Kicks off the region-locked shop meta and introduces "resident vs traveler" NPC dialogue paths.
Full breakdown in the Citizenship guide - cover story quests, grade thresholds, and switching-cost math.
Crafting
Also not a traditional MapleStory system. Weaponcrafting + Woodcrafting kits let you assemble gear from datamined ETC drops and materials. Ties into the "never sell ETC" beginner advice hard - if you sold your Leaves at Lv 12, you can't craft the Lv 15 gloves at Lv 18.
Full breakdown in the Crafting guide - all recipes, material sources, and cost math.
First-job skill changes
CoT 2 keeps most traditional MapleStory first-job skill kits intact but there are confirmed changes on two classes. Full details in the Skill Changes guide. Summary:
- Warrior: gained a new 6th passive skill Precise Strikes (accuracy + crit rate). Other 5 skills unchanged.
- Bowman: lost Blessing of Amazon (the traditional MapleStory party attack buff), gained Power Knockback (crowd-control AoE that always crits). Significant build re-think for returners.
- Magician + Thief: all six first-job skills match the traditional MapleStory baseline exactly. No changes. (Datamine calls Thief "Rogue" internally, but the visible class name is unchanged.)
EXP curve shifts
Both mob EXP and quest EXP values in the datamine differ from commonly-cited traditional MapleStory numbers, though the shifts are inconsistent (some go up, some down, some stay the same). This is the least settled area right now - we know the numbers are different but we don't have a confirmed pattern.
Full analysis in Then vs Now: EXP & Progression - includes concrete mob EXP examples pulled directly from the datamine.
What HASN'T changed (that you can still trust)
Not everything traditionally muscle memory is worth un-learning. Verified identical to traditional MapleStory in the CoT 2 datamine:
- Class advancement flow: Beginner → job at 8/10, 2nd job at 30, 3rd job at 70, 4th job at 120. Same NPCs (Dances with Balrog, Grendel, Athena Pierce, Dark Lord) in the same towns.
- Base stat mechanics: STR/DEX/INT/LUK all work the same. HP/MP AP allocation, HP/MP washing mechanics, equipment stat scaling all unchanged.
- Item categories + IDs: Every traditional MapleStory item ID that carried over kept its ID. Red Potion is still 2000000. Chaos Scroll is still Chaos Scroll. Set bonuses still exist.
- Quest flow archetype: Talk-to-NPC → collect-N-of-X → return-for-EXP-and-mesos. Structure identical; the specific quest numbers just shifted.
- Magician + Thief first-job kits: as noted above, no changes for these two classes.
What we don't yet know
Honest gaps in current knowledge:
-
Exact party EXP formula. The traditional MapleStory formula was
0.6/partySize + 0.4*(memberLv/totalLv)- our Party EXP guide uses it as a working assumption, but we haven't confirmed CoT 2 uses the same math. Nexon may have retuned the party bonus curve. - Which classic PQs actually ship at launch. Kerning PQ is confirmed. Ludibrium PQ, Amoria PQ, Ludi Maze, Orbis PQ, Herb Town PQ, Guild PQ - all TBD until we're on live servers to check the NPC roster.
- 2nd + 3rd job skill kits. Datamine has the skill files but we've only surfaced the 1st-job changes so far. 2nd job class-splits (Fighter/Page/Spearman etc.) and beyond will need a second pass.
- End-game boss lists. Partly answered: per the Grand Launch release notes, none of Zakum, Horntail, or Pink Bean are in at launch - the six launch bosses are all on Victoria Island. Retunes and later additions are still a blank slate.
- Meso drop rates + mob EXP live-server values. Datamine gives us declared values but Nexon's live tuning multipliers (event bonuses, base rate changes) aren't in the client files.
Suggested reading order for returners
- This page, first - get the "what's actually different" overview under your belt.
- Skill Changes Per Class - before you commit to a class based on traditional MapleStory memory, check what changed in the kit.
- Then vs Now: EXP & Progression - understand which of your grinding-spot memories still apply.
- Citizenship and Crafting - the two new systems that have zero traditional MapleStory analog and gate serious progression.

This page is a living document. As we find live-server tuning that differs from the CoT 2 datamine, the deltas get logged here first, then propagated to the affected guides. Bookmark it if you're returning from an old GMS character - it'll save you a class-rerolling reset.
