I'm want to create the hidden blade from assassin's creed brotherhood (video game)
I created the model and stuck on how to create engravings on the hand guard of hidden blade
Here are some reference pictures

The engravings on the blade doesn't has that much of a bump to them, so I'm going to add them in textures
But ones on the hand guard does
So my question what options do I have to make them?
I want it to be details just like in the first picture
So I don't think a texture with a bump map will do
PS: Still a noob in blender so... sorry if this question is stupid
