This mod adds an extra state before entering the x-ray view where talion turns into a Nazgul, while the rest stays the same.
For a better understanding just watch the video(s).
Also works with Eltariel and Celebrimbor.
This mod was written for the steam version. GoG doesn't work.
Change the language in steam to english or german. Otherwise the mod won't find the main ShadowOfWar window.

V5.1:
Fixed the hook at 0x14051A978 which caused random crashes.
Fixed the small splash (will get a better fix in a later version. Atleast it doesn't disturb anymore)

V5.2:
Fixed the infinte might function which caused random crashes at startup

V6:
Fixed infinite might: Changed the infinite might pointer to a hook --> shouldn't cause any problems anymore
Fixed the issue that Nazgul powers won't work even if you are in Nazgul presence 
--> You need to configure a new key in the .ini (it needs to be the same key you are using in the game to toggle xray view)
Added infinite focus (also a hook so there shouldn't be any issues)

V6.1:
Added dynamic signature scans instead of fixed addresses to avoid problems with the hooks.

V6.2:
Removed the splash and the message box at the beginning. It's now compatible with ReaperAnons Mod Loader!

Installation:

Get the DLL Loader and put the Nazgul.dll into the plugins folder

V4:

Paste the Nazgul.ini next to ShadowOfWar.exe

V5 - CURRENT:

Delete the Nazgul.ini file next to ShadowOfWar.exe (if you previously installed V4. Otherwise you can skip this step)
Extract the Archive into the plugins folder.
After that you should have the Nazgul.dll next to the Nazgul folder

Known bug(s):

After entering elven rage you will stay a nazgul.  Workaround: Make sure you are NOT in Nazgul presence before activating elven rage

In some rare cases after climbing the Nazgul powers won't work anymore. Workaround: Turn Nazgul presence off and on

This mod is in a very very early state. Please expect bugs and give me the time to fix them.
