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 Changed 62 Removed 97

Two new: Shade, a level 48 boss in the Cabin of the Forsaken, and the Orange Slime. Ninety-seven gone: the 40 that spawned only in Ossyria, and 57 the second test carried with no map to spawn on. Of the 62 revised, 40 give less EXP and 7 more (King Slime went from 248 to 2,400), 39 are harder to hit, and Zombie Mushmom went from level 50 to 55.
