The following is a guide on how to paint the Ballistus dreadnought from the leviathan box set in the colours of Baal.

Basecoat main body + legs

1. Start by undercoating the model with Mephiston Red . This can also be done as a spray.
2. Basecoat any black parts with Abaddon Black . Make sure to slightly thin it with water so it gets onto the model smoother.
3. Basecoat any silver metal parts with Leadbelcher . Refer to the image for help.
4. Basecoat the rock the dreadnought is standing on with Rakarth Flesh . Paint the entire rock with this.
5. Paint any purity seals and parchment with Wraithbone . Also paint the wax head.
6. Basecoat the exhaust pipes on the back of the model with Balthasar Gold . Also include the pipes and bullet shells on the rock too.
7. Paint the sarcophagus with Retributor Armour . Refer to the image for help.
8. Basecoat the light on the dreadnought with Corax White . Any white works for this.
9. Paint the tyranid things on the base with Naggaroth Night . Try to avoid the Rakarth Flesh as much as possible.

Shading main body + legs

1. Recess shade the red armour with Agrax Earthshade . Use the tip of your smallest brush for this.
2. Wash the top 2 thirds of the exhaust pipes with Agrax Earthshade . Leave the lowest third.
3. Wash the rock with Agrax Earthshade . Also include the pipes and shells.
4. Wash the purity seals and parchment with Agrax Earthshade . Try to avoid spilling the paint onto the rest of the model.
5. Shade the sarcophagus and pipes with Agrax Earthshade . It is fine if you accidentally paint the silver.
6. Shade all the Leadbelcher with Nuln Oil . Avoid the red armour as much as possible.
7. Wash the rock with Nuln Oil to darken it.
8. Shade the topmost third of the exhaust pipes with Nuln Oil . You may have to do a few coats to see a difference.
9. Wash the light and some pipes with Frostheart . Aim for every second pipe.
10. Wash the wax on the purity seals with Magos Purple . Avoid the parchment on the seals.

Layering and highlighting main body + legs

1. Edge highlight all the red armour with Troll Slayer Orange . Use the edge of your brush for this.
2. Edge highlight all silver metal and gold parts with Stormhost Silver . Optionally use this paint to highlight the black. Include any parts painted with Balthasar Gold .
3. Paint thinned Yriel Yellow onto the light that is split into 9 sections.
4. Carefully paint lettering onto the parchment on the dreadnought's leg with Abaddon Black . This can be very difficult though.

Basecoat front

1. Undercoat the sub section with Mephiston Red . This can also be applied using a spray.
2. Paint the black part with Abaddon Black . Thin with water for a smoother application.
3. Basecoat the parchment and purity seals with Wraithbone . At this point my Wraithbone paint dried out so I swapped to using Flayed One Flesh . I got an almost identical result.
4. Basecoat the crux terminatus with Corax White . Be very careful not to accidentally paint the red armour.
5. Paint the aquila with a 1:1 mix of Abaddon Black and Leadbelcher . Darker silver paints also work.

Shading front

1. Recess shade the red armour with Agrax Earthshade . You will need a thin brush for this.
2. Shade the parchment and purity seals with Agrax Earthshade .
3. Shade the crux terminatus with Nuln Oil . You may have to apply this twice to get the darkness your looking for.
4. Wash the aquila with Nuln Oil . Be sure it doesn't fill in the recesses to much.
5. Paint the wax head on the purity seals with Magos Purple . Avoid the parchment.

Layering and highlighting front

1. Edge highlight the red armour with Troll Slayer Orange . Apply twice for a brighter orange.
2. Edge highlight the aquila with Stormhost Silver . This can also be done as a careful drybrush.
3. Edge highlight the crux terminatus with White Scar .
4. Use thinned Abaddon Black to add lettering and detail onto the parchment. Do this with the parchment on the purity seal too.
