The low-poly bake can be viewed in real-time here. Helmet model has 32k tris. The final ZBrush sculpt had about 7 million polys.

I implemented the helmet in my own Crusader Kings 3 mod. Here it is seen in the Clausewitz Engine: You get access the steam mod here: https://steamcommunity.com/sharedfiles/filedetails/?id=2543592294

Vampire Gaze was a "unique" item in Diablo 2. In preparation for the Diablo 2 remaster, I decided to put my own spin on the legendary item. Starting from referencing the original in-game images of vampire gaze, I designed and built a higher resolution view of what it could be. The low poly model has 32,000 triangles.
I have also used this to create my own mod for Crusader Kings III that allows players to wear the helmet. It is rigged and has blendshapes. You can find the mod here: https://steamcommunity.com/sharedfiles/filedetails/?id=2543592294
