+ 1,312 more removed entries not listed here. They're in the full diff file.

How to read this: entries are matched by the game's own IDs, so a renamed item shows as changed, not as removed and added. Values are shown exactly as the files hold them ("none" means the field was empty). Names link to our database page when the entry is live in Classic World; test-only, hidden or removed entries are plain text. Program code changed too (16 functions added, 39 changed, 7 removed), but code isn't readable as game data, so it isn't listed. Server-side data like drop rates never appears here.

FAQ

What changed in the Closed Online Test 1 patch · Apr 13 build?

Comparing the two clients entry by entry: maps: 2 changed; quests: 3 changed; item: 1 changed; game text lines: 1,712 removed. In total 0 added, 1,712 removed and 6 changed.

Which builds are compared?

COT1 launch (1e3d2d3b) (archived Apr 6, 2026) against COT1 patch (4237b973) (archived Apr 13, 2026), both read from the game client files.

Does this include drop rate changes?

No. Drop tables, event switches and spawn timers live on Nexon's servers, not in the client, so a client comparison can't see them.
