Here's my custom order minoris - Order of the Thorn. Special thanks to Bobby Clarke (Red Eagle Studios) for helping me figure this out.

Silver Armor

1. Spray Leadbelcher
2. Wash all over with Nuln Oil
3. Drybrush all over with Runefang Steel . Don't overdo it. You want almost no paint on your brush and make sure the bottle is shaken first, or it'll go milky.
4. Hit the very darkest shadows with very slightly watered down Black
5. Get all edges with Stormhost Silver

Gold

1. Retributor Armour
2. Guilliman Flesh
3. Sycorax Bronze (drybrush)
4. German Camouflage Black Brown (pin shadow)
5. Stormhost Silver (pin highlight)
6. ⚠️ Shortcut alert: For tiny gold elements like buckles and pistol icons, you can usually get away with just a basecoat of Retributor Armour and a highlight of Stormhost Silver

Guns

1. Basecoat Khorne Red
2. Wash Nuln Oil
3. Hit exposed panels again with Khorne Red , making sure not to erase any of the nuln oil shadows.
4. Shade from middle to bottom of panels with Mephiston Red
5. Shade bottom of panels. Wild Rider Red . The goal is to make a three-color transition, with Khorne at the top, Mephiston in the middle and Wild Rider at the bottom.
6. Create a small edge shadow at the top with German Camouflage Black Brown . On pistols this will hardly be visible.
7. Edge highlight top and side panels with Troll Slayer Orange

Blue Backpack Panels

1. On your palette, make some blobs. Pure Kantor Blue , AK Blue Green, 50/50 Ak Blue Green and Kantor, Pure White , Pure Repear Surf Aqua.
2. Basecoat the panel with the 1:1 Kantor Blue , AK Blue Green mix.
3. Shade top left corner with pure Kantor Blue and make a transition.
4. Shade bottom right corner with AK Blue Green and make a transition.
5. Dot in top left of White - don't cover all of Kantor blue with it.
6. Line highlight bottom left and part of bottom of panel with Surf Aqua.

Leather

1. Basecoat all leather Rhinox Hide .
2. Wash Nuln Oil
3. Large highlight Mournfang Brown
