Base coat

Lay the foundation colour down over primer, slightly darker than the final tone.

Also:
2

Shade

Wash the recesses to add depth and separate the details.

Also:
3

Layer

Rebuild the main colour on the raised areas, leaving the shade in the cracks.

Also:
4

Highlight

Pick out the upper edges and surfaces that catch the light.

Also:
5

Edge highlight

Sharpen only the sharpest edges for a crisp, finished look.

Also:

Details & accent colours

Everything else on the model - metals, skin, leather, lenses, basing and this faction's signature accents.

Metal — trim

Trim and bare plate. Basecoat steel, wash dark, then edge bright silver.

Also:

Metal — weapons

Bolters, blades and casings. Dark gunmetal, washed black, edged with bright steel.

Also:

Leather & pouches

Straps, holsters and bare wood. Mid brown, shaded, then drybrushed a lighter tan.

Also:

Skin & flesh

Faces and hands. Basecoat, a flesh wash into the recesses, then build the highlights back up.

Also:

Eyes & lenses

Lenses, eyes and energy. A bright spot colour that pops against the armour - dot it on and add a white glint.

Also:

Basing — earth

Groundwork. Earth basecoat, drybrushed bone, finished with your choice of grass, sand or snow.

Also:

Gore & wounds

Glossy deep red in wounds, mouths and exposed guts - wet rot against the matt armour.

Also:

Rust & corrosion

Stipple orange-brown around rivets, vents and lower edges. Vary the tone so it reads as organic decay, not a flat colour.

Also:

Grave-soil & filth

Mud and corpse-earth caked on everything below the knee - stipple and drag, do not tidy.

The Black Grail is Trench Crusade at its most nightmarish - a plague of corrupted flesh and shambling body horror boiling out of the ground where the war is at its worst. There is barely a uniform in sight: this warband is rot, sinew, grave-soil and gore. That makes it the single most forgiving project in the game, because - as with any decay-themed force - mess is the point. Pooled washes, uneven layers and heavy-handed stippling all read as more corruption.

The signature look

The base tone is a putrid grey-olive - dead flesh and rotten cloth blurring into one another - built from the recipe above. Over that you layer three kinds of horror: pallid, sickly skin on exposed flesh; wet crimson gore in wounds and mouths; and grave filth - dark corpse-earth caked over everything below the knee. Any metal present is scrap, and should be more rust than iron.

Painting the rot

  1. Basecoat everything - flesh, rags, hide - with the putrid olive ramp, keeping the tones muddled rather than neat.
  2. Drench the model in washes. Brown in the recesses, a touch of green over larger flesh areas, purple or red glazes around wounds and swollen tissue. Let them pool; the washes guide explains why that works here.
  3. Drybrush the raised areas back up with pale bone-olive - see drybrushing - so the texture of the sculpt does the shading for you.
  4. Pick out pallid skin in a lighter sickly tone so the anatomy reads at arm's length.

Gore and wounds

This is where the Black Grail earns its horror. Paint wound interiors, mouths and exposed guts in deep red, shadowed to near-black at the deepest points, then gloss them - either gloss varnish or a dedicated blood technical paint. The wet shine against the dry, matt rot is the single most effective contrast on these models. Thin tendrils of gore dragged from a wound with a fine brush add motion, but a little goes a long way.

Grave filth and weathering

Where other warbands are weathered, the Black Grail is buried. Stipple and drag dark corpse-earth up shins, hems and trailing flesh - do not tidy it. Follow with a lighter dried-mud drybrush at the very bottom so the filth has depth. Rusty scrap metal - blades, hooks, buckles - gets orange-brown stippled over dark gunmetal with almost no clean metal left showing. Base the warband on churned grave-dirt with pooled water effects if you like; the basing guide covers muddy ground and water.

Tips and common mistakes

  • Let the washes pool. On most armies pooling is a mistake; here it is texture. Lean into it.
  • Matt rot, gloss gore. Keep the body dead and dry so the wet points of red genuinely shock.
  • Vary the flesh. Shift the skin tones between models - grey, green, jaundiced - so the horde looks like many corpses, not one repeated one.
  • Stop before you polish. If you find yourself neatening an edge, put the brush down. The Black Grail is the rare scheme that careful technique can actually make worse.
