I could extract the inscription from the lod model's cloak and attach it to the regular one, but I won't do that work for just 1 out of 4 elements (I tried to make a ruby for the sword, but since I have zero knowledge in 3D modeling, I couldn't do it).
I doubt they just sloppily drew it on the texture; it's actually volumetric on the vampire princes.

But it needs to be edited now because it's a bit blurry.
