Hallo, little question. Folder with name custom in game\data\stats\items\
How it must been used for new items? And how it works?
For example I need new dual swords, how I can do it?

You make a custom item in the game client, let's say, ID 30000 (nobody will discuss it here, not legal), then check an existing item's data, make a new xml (30000-30100.xml) and put your new item's stats there. That should be it.

thx
