1. Prime Chaos Black
2. Heavy overbrush with Thrash Metal
3. Wash all the metal with a heavy coat of vallejo enviornment rust texture
4. Drybrush Thrash Metal
5. Lightly drybrush Speed Metal
6. Stipple Waaagh! Flesh onto laser rifle chassis, Averland Sunset on the power cell, and a lil Mephiston Red on the front port. The BoS Core Box knight has a gatling laser - here, I used Old Copper and more red on the chassis to approximate the in-game look.
7. Wash armour joints, weapons and darker details with Basilicanum Grey . Colour the visor in with Black Legion
