1. Update your client version to 3.3.5a.

You can download the patches using the link below: Patch mirrors (wowwiki) or wow-patch.in (after downloading this patch, it has to be moved to the location of your game. You will have to open your 'World of Warcraft' folder on your computer and copy/paste it.

2. Editing the Realmlist

2.1. How to: Open the installation folder of the game (your World of Warcraft folder). In subfolder “\Data\enGB” (respectively \Data\enGB depending on your game version) you will find a file named 'realmlist.wtf”. Now open this file using a text editor e.g. Notepad.

Note: In case your Windows is not configured to show the file extensions, your realmlist file would probably appear as “realmlist”.  Open the realmlist file for editing.

2.2 Please change the row starting with “set realmlist” to: “set realmlist 212.116.136.130”, no quotes

2.3. Press “Ctrl+S” or click File > Save from the File Menu. Now you have configured your connection to Nefelin WoW Server.
Note: In case you cannot save the file after the change, you probably don't have the required permissions or the file is Read-Only and you will  have to change the Read-Only setting.

3. Download & Installing the LACD (Lost Angel's Cheat Death) client!

The most important thing is the client which enables your connection to our server. LACD starts the game automatically and is constantly monitoring your game and preventing the usage of any hacks or cheats (You won’t be able to connect without running the game through the LACD client)

3.1. Download the client: A download link for the LACD client. You can also visit this page. http://forum.nefelin.com/viewtopic.php?p=317059

3.2. After the download is complete, you have to open your “World of Warcraft” folder and place it there. (You will have to unzip the file and paste it in the game installation folder (where the file wow.exe is).

3.3 Download the file http://leviathan.nefelin.com/realmlist-nef-test.zip and unzip in the game installation folder (the file realmlist.wtf from the archive must be placed in the same folder as the LACD and wow.exe) Press the right mouse button on the LACD, a drop-down menu appears. Press “Copy”, then go to the folder where you want your LACD shortcut to be placed and click on “Paste Shortcut”.
