The magician must somehow be correlated with the tower. This techno-magic and mysticism would not be in the subject, because modern technology seems to be Aborigines magic. I made mechanical dogs that can help the magician. These dogs are inside the tower.
In ZBrush is very convenient to paint scrapes with polypaint. You can make a mask in the form of the model, which further speeds up the job ("mask by cavity"). The resulting texture is good to use as a texture map blending 2 materials in 3ds max.
The ground and stones, I did completely in ZBrush. I tried more textures in ZBrush, and unwrapped it in almost all the models.
