Several years ago the Neverwinter Nights Client Extender (NWNCX) was created. It is a set of files that modifies the player-side game client software. NWNCX is designed to improve the base game for players, and one I recommend everyone download and use.
Please note though that NWNCX is not necessary for the Thay PW, except in these cases:
1. If you wish to create a new Cleric that has the Luck, Chaos, or Law domain
2. If you wish to create a new Paladin that has the Detect Evil ability
3. If you wish to create a new Ranger that has the Tracking ability
4. If you wish to put skill points in Control Shape, Disguise, or the Craft skill upon initial character creation
Those three Cleric domains, the Paladin Detect Evil ability, and the Ranger Tracking ability are custom content added for the Thay PW which are not included with the original game. In addition, the three skills listed are renamed via Thay's custom content from their original implementation in NWN (they were originally the three NWN crafting skills).
So in order to see the above custom content changes at character creation you must use the functionality that NWNCX provides to pre-load the Thay PW’s custom content before you create a new character. To do this, just download the NWNCX package from the link above and then extract the nwncx_connect.dll and the NWNCX_Loader.exe files from it to the C:\NeverwinterNights\NWN folder. Then launch the NWNCX_Loader.exe and connect to the Thay PW.
Note that when the nwncx_connect.dll file is in the NWN folder, using NWNCX to login to any NWN server that has this custom content pre-loading enabled will result in a noticeable delay when waiting for your list of characters to populate when you login. This is occurring because the server’s custom content is being pre-loaded. As for Thay, after you have created your new character I recommend removing the nwnx_connect.dll from your NWN folder to avoid the ‘lag’ that occurs waiting for your character list to populate whenever you login to the server.
