MapleStory Classic World client changelog: Closed Online Test 1 to Closed Online Test 2
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. Some of what arrived, like Orbis and 3rd job, was held back from the Public Release; this site keeps those pages, marked CoT2.
Closed Online Test 2 is dated 4 August at the end of the older diff and 11 August at the start of the newer one, and both are right: the first was made from the build the test opened on, the second from the one its 11 August balance maintenance left. What that maintenance changed (Rush’s cooldown went from 3 seconds to 1, for one) is in neither diff.
From the OSMS Data Explorer datamine of 5 August 2026. More on the sources.
The changes most likely to have been felt while playing. Accuracy, HP, attack and knockback were all retuned, and every monster keeps its own row.

Almost all of the additions are 3rd job, which arrived with the second test. The revisions are where a skill you already had changed under you.

A defence pass, mostly: 798 of the 802 revised rows carry a stat change, 749 of them touch DEF, and for 633 the defence number is the only thing that moved at all. Only 20 are renames, which is why each field is shown separately rather than summarised.

The largest single movement in the file, and the least meaningful: the second build re-listed the shop wholesale. Most of the removed rows are unnamed placeholder slots that carried an id and nothing else. Prices in the second test were beta placeholders, not final.
