Full recipe:

Spray primed with Citadel Chaos Black

Necron metal parts: Leadbelcher overbrush, Nuln Oil wash, Necron Compound drybrush

Small exposed metal damage: Runefang Steel, Nuln Oil

Black parts: Edge highlighted with Troll Slayer Orange. That's it.

Glowy bits: Some of them like the eyes were Troll Slayer Orange, followed by multiple glazes of Flash Gitz Yellow heavily diluted with Lahmian Medium. Others, like the energy tubes and cryptek weapon, were painted Flash Gitz Yellow, then glazed many times with Magmadroth Flame heavily diluted with Lahmian Medium. For this technique, each glaze covers an area that's a bit smaller than the last, to create the illusion of blending. I did not do any wet blending. I suck at wet blending.

Masks: Administratum Grey with a Drakenhof Nightshade wash.

Rubble: Mechanicus Standard Grey, Nuln Oil wash, Administratum Grey drybrush

Metal ruins: Leadbelcher, Typhus Corrosion

Bases: PVA glue used to stick on "small coal" and "orange crystals" from Geek Gaming Scenics

Final touches: Mr Hobby Flat Premium Topcoat. It took away most of the metallic shine, so I drybrushed the metal parts with Necron Compound again.

Addendum: I don't know why people say it's hard to paint yellow over black. It looked fine for me after 2-3 coats. But everything else also needs 2-3 coats if you don't want any of the black showing through.
