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. What the release left out of the second test is not missed but listed under Removed: Ossyria and 3rd job among it, which Nexon held back for later. This site keeps their 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 6 October 2026. More on the sources.

New 2,373Changed 175Removed 13The largest section by count and the smallest by effect: 2,373 new catalog lines and only two of them on sale. Of the 175 revised, 98 went off sale and 29 on, and 162 had their price changed. The 13 removed were unnamed lines with an id and nothing else.
