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 6Changed 111Removed 127

All 92 maps of Ossyria are gone, and 32 of Forgotten Hollow’s 33 with them, along with two developer test rooms and an old copy of Victoria Road: 127 in all. The one Forgotten Hollow map the release kept, Someone Else’s Grave, lost its name in it. The six new ones are on Victoria Island, Shade’s cabin among them. 103 of the 111 revised maps changed their mob rate, 65 down and 38 up.
