MapleStory Classic World client changelog: Public Release to the Grand Launch
Read from the client: the Grand Launch of 21 October 2026 against the Public Release of 6 October 2026, 242 additions, 227 removals and 291 revisions. New: 17 monsters with Stumpy and Faust among them, 31 maps, the Excavation Site among them, 38 items, 27 quests and 18 recipes. Removed: 227 Cash Shop catalog lines, none of them on sale.
Upstream’s datamine did not publish a diff for this build, so this site compares its two exports itself, in the shape the datamine’s own diffs take. The Public Release’s changes are one build back: Closed Online Test 2 to the Public Release.
About this page
What it is
Two client exports compared field by field, not Nexon’s patch notes, so it shows changes nobody announced. It can’t say why something changed: a typo fix and a rebalance look the same.
What it misses
Drop rates, shop stock and quiz answers live on the server, so they never show up here. Stumpy and the Excavation Site arrived in this build, so they are in it; anything the server switched on without a client change is not. What the Public Release left out of the second test is in the diff before this one, and its pages are kept here, marked CoT2.
Written by this site from two exports of the OSMS Data Explorer datamine, the Public Release as frozen on 6 October 2026 and the Grand Launch as pulled on 21 October 2026. More on the sources.
Monsters17 new
New 17Changed 15Removed 0Seventeen new. Two bosses: Stumpy, level 35, in the new Parched Land, and Faust, level 65, with no spawn in the export. Eight for the Excavation Site: Ghost Stump, Wooden Mask and Rocky Mask on the dig itself, and Skeledog, Mummydog, Skeleton Soldier, Officer Skeleton and Commander Skeleton (level 73) in the Remains and the camps. Five arrived ahead of the Moon Bunny’s Rice Cake party quest, which the roadmap puts on 18 November: the Moon Bunny, and two Stirges, a Flyeye and Goblin Fire on Primrose Hill. And another Flyeye and a training dummy, with no map. Of the 15 revised, nine spawn somewhere new, Lupin and Tortie attack every 5 seconds instead of 3, and five are harder to knock back: Copper Drake, Tortie, Drake and Red Drake twice as hard, Wild Kargo three times (375 to 1,125). The export also stopped writing the regular 7.56-second respawn on each spawn; that is a change in the export, not the game, and it is not counted here.
