Bloodstone Visage display bug
I have the same problem, plus even more annoyingly, for me the effects only show up properly on the hero panel, but not on the in game character model.
Here is a screenshot of my Asura necromancer to illustrate the problem.
The quality isn’t very good unfortunately but I think you can tell that the effect is visible on the hero panel, while on the in game model only the eyecolor has changed but in a much more subtle way.
Interestingly enough when i move my character close to a wall or other obstacle and turn the camera so I can see their face up close the effects whill appear suddenly.
If you so desire, you can change your Shaders to cause the Visage to show up in-game.
Good luck.
