For the size of the models the terrain was pretty quick to paint. The rock, walls and roofs are mainly over brushing and dry brushing. I made my own washes that helped a ton on cost long term. 10% flow aid, 50% matte medium, and 40% sterilized water. Color to taste with acrylic inks. I used a bit of green, brown, and black to get my wash for most oathsworn stuff.
