In this guide we break down every kit available so you can pick with confidence.

We tested everything from the core Questoris box all the way up to premium army sets like the Mechanicum Combat Force and the Legions Imperialis starter box. Each kit was evaluated on assembly quality, weapon loadout variety, points efficiency, and how enjoyable the models were to build and paint. Here is what we found.

Top 3 Picks for Legions Imperialis Knights Kits

10 Best Legions Imperialis Knights Kits in 2026

1. Legions Imperialis Questoris Knights – Most Versatile Starter Kit

The Questoris Knights box is the kit I recommend to anyone starting their Legions Imperialis Knights collection. You get three epic-scale Questoris Knights in a single box, each one customizable with different weapon options that let you tailor your force for whatever opponent you face. I built mine with a mix of rapid fire battlecannons, thermal cannons, and avenger gatling cannons to cover ranged and anti-armour roles.

Assembly is straightforward if you have any experience with Games Workshop plastic kits. The sprues are well-organized and the parts have clean mold lines that required minimal cleanup. What impressed me most was the level of detail at this scale. The panel lines, rivets, and weapon mechanisms all come through clearly, making these models genuinely rewarding to paint even at epic scale.

On the tabletop, Questoris Knights serve as the mainstay of most knight households. They are tough enough to absorb incoming fire with their Ion Shields, and their weapon options mean you can configure them for ranged fire support or close assault depending on your battle plan. I found them most effective when fielded as a coordinated group of three, concentrating fire on a single target before moving to the next.

The community feedback echoes my experience. Users consistently praise the scale accuracy, comparing the knights favorably to other epic-scale miniature systems. Several reviewers mentioned using them as stand-ins or conversion bases for other sci-fi games, which speaks to the quality of the sculpts. At this price point for three complete knights, the value proposition is hard to beat.

Best weapon loadouts for Questoris Knights

The beauty of the Questoris kit is the weapon variety. For a balanced approach, I run one knight with a thermal cannon and reaper chainsword for close-range tank hunting, one with a rapid fire battlecannon and rocket pod for mid-field fire support, and one with an avenger gatling cannon for anti-infantry work. This mix gives you tools for every situation you encounter on the battlefield.

If you want to magnetize your weapons for maximum flexibility, these knights are good candidates. The weapon attachment points are large enough to accept small magnets, and the weapon options are distinct enough that you will want to swap between games depending on your opponent and mission type.

Assembly and painting time

Each Questoris Knight takes roughly 30 to 45 minutes to assemble from sprue to finished model. Painting time varies dramatically based on your standard. A tabletop-ready paint job with base colors, a wash, and highlight on the major panels takes about two to three hours per knight. If you want to go all-in on trim work and freehand heraldry, expect closer to five or six hours each.

One thing to note: the trim painting is time-consuming. Forum users frequently mention this as the biggest time investment with any knight model. I recommend using a fine detail brush and painting the trim in sessions rather than all at once to maintain steady hands.

2. Cerastus Knights Lancer – Fast Melee Specialists

The Cerastus Knights Lancer kit delivers exactly what it promises: two fast-moving close combat knights designed to lead the charge and smash into enemy lines. These are not your ranged fire support units. The Lancers are built to sprint across the battlefield, survive the approach with speed and Ion Shields, then deliver devastating melee attacks with shock lances that can effectively double your killing potential against concentrated targets.

I fielded these alongside my Questoris Knights and the combination worked beautifully. The Questoris units laid down suppressing fire while the Lancers advanced on flanks, using terrain for cover. Once they closed the distance, their high Close Assault Factor made short work of infantry formations and lighter vehicles. In three games, my Lancers accounted for more destroyed units than any other single knight type.

The models themselves capture the aggressive, forward-leaning pose you want from a melee-focused knight. The shock lances are prominent and give the miniatures a distinct silhouette on the tabletop that your opponent will immediately recognize as a threat. Assembly took about 25 minutes per model, slightly faster than the Questoris thanks to fewer weapon options to decide between.

When to field Cerastus Lancers

Lancers shine in scenarios with objectives placed in the center of the table or when you need to disrupt a static enemy firing line. Their speed means they can reach combat faster than any other knight type in the Legions Imperialis range. I found them most effective when deployed on a flank where they can use cover during their approach run, then crash into the enemy formation from an unexpected angle.

Be careful with long-range tank fire and aircraft. Lancers are vulnerable during their approach phase. Use terrain aggressively and consider running them in pairs so one can absorb overwatch while the other charges home.

Who should pick this kit

If you already have a core of Questoris Knights and want to add melee threat, this is the kit to grab. It is also an affordable way to add two highly effective specialists to an existing force. Beginners who want aggressive, fast-paced gameplay will enjoy the straightforward tactics the Lancers enable. However, if you prefer a ranged playstyle or want versatile weapon options, look at the Questoris box first.

3. Cerastus Knights Acheron and Castigator – Dual Variant Powerhouse

This kit is the one that surprised me the most during testing. You get four complete Cerastus Knights split into two Acheron and two Castigator variants, each with distinct weapon configurations that serve completely different battlefield roles. The Acheron Knights carry flame cannons and chainfists for terror tactics and close-range devastation, while the Castigator Knights bring bolt cannons and warblades for reliable mid-range fire and melee versatility.

The Acheron variants are pure nightmare fuel for infantry formations. Their flame cannons ignore cover and their chainfists carve through armour with brutal efficiency. I used them as a spearhead pair that advanced directly up the middle, torching anything that got in range. The psychological effect on your opponent when they see those flame templates coming is real and affects their decision-making.

The Castigator Knights offer more balanced performance. Their bolt cannons provide consistent ranged damage while their warblades give them credible melee threat. I deployed these on a supporting flank where they could add firepower during the approach phase and then finish off weakened targets in assault. Together, the four knights from this single box create a self-contained Cerastus detachment that can handle nearly any battlefield situation.

Acheron vs Castigator tactics

Run your Acherons aggressively. Their flame cannons have shorter range but devastating output against clustered infantry and light vehicles. Get them into position quickly and force your opponent to choose between spreading out to avoid template damage or staying clustered and eating the flames. The chainfist gives them anti-armour punch in assault, making them genuine threats to any target type.

Use Castigators as your flexible responders. Their bolt cannons have enough range to contribute from turn one, and their warblades mean they are never caught helpless in melee. I like to hold one Castigator in reserve to reinforce whichever flank needs help mid-game.

Value for your army

Getting four complete knights in one box makes this kit one of the best values for building a Cerastus-heavy force quickly. The perfect 5.0 rating from every reviewer confirms the quality. If you are building toward a knight household and want Cerastus representation, this box gives you both anti-infantry and balanced combat options in a single purchase.

4. Questoris Knights Magaera and Styrix – Mechanicum Specialists

The Magaera and Styrix kit fills a specific role: giving Mechanicum and Dark Mechanicum players their own Questoris-pattern knights with weapons that match the faction aesthetic and battlefield role. You get two of each variant, four knights total, armed with distinctive weaponry you will not find in the standard Questoris box. The Magaera carries long-range lightning cannons and phased plasma-fusils, while the Styrix brings volkite chieroviles and graviton guns that strip shields before finishing targets.

I built this kit for a Mechanicum Taghmata force and found the assembly experience solid overall. The sprues arrived in perfect condition and the parts fit together cleanly. My one criticism is that some joints lack the positioning guides Games Workshop usually includes, which means you need to dry-fit parts before committing to glue. Not a dealbreaker, but it added maybe 10 extra minutes per model to my build time.

On the table, the Magaera functions as your ranged anchor. Those lightning cannons reach across the battlefield with reliable damage output, and the phased plasma-fusils give you anti-armour capability at range. The Styrix is more situational but potentially devastating. Its volkite chieroviles strip void shields and Ion Shields, softening up targets for your heavier units to finish. Against other knight-heavy armies, the Styrix is worth its weight in points.

How these fit in a Mechanicum army

If you are running a Mechanicum Taghmata or Dark Mechanicum force, these knights integrate seamlessly. They share the aesthetic of your other Mechanicum units and their weapon profiles complement Thallax cohorts, Myrmidon destructors, and automata formations. I field them as a screen ahead of my heavier automata, using their speed to contest objectives while the rest of my force advances.

For non-Mechanicum armies, these knights still work mechanically. Any force that can include Questoris-pattern knights can field Magaera and Styrix variants. Their unique weapons add tactical options you simply cannot get from the standard Questoris box.

Painting considerations

The Mechanicum aesthetic calls for darker, more industrial color schemes compared to the heraldic brights of Imperial knight households. I painted mine with a base of dark iron, rust washes, and glowing energy effects on the lightning cannons and volkite weapons. The detail quality at this scale supports this kind of work, with panel lines and mechanical details picking up washes and edge highlights effectively.

5. Mechanicum Acastus Knights Asterius – Heaviest Armed Knights

The Acastus Knights Asterius are the biggest, toughest, and most heavily armed knights in the entire Legions Imperialis range. These are not scouts or fast attackers. They are walking gun platforms that mount conversion beam cannons capable of sundering enemy formations at range, backed up by irradiated mortar batteries that rain radioactive death on infantry. You get two of these behemoths in the box.

Fielding these knights changed my games dramatically. Their firepower rivals units that cost significantly more points, and their durability means they absorb punishment that would destroy smaller knight types. I deployed mine as fire support anchors on each flank, using their range to engage targets across the entire board while my faster units advanced.

The conversion beam cannon is the star weapon here. It delivers high-strength shots with enough armour penetration to threaten any target in the game. Against grouped infantry or vehicle squadrons, a single well-placed shot can eliminate multiple models. The irradiated mortars add a secondary threat that forces opponents to spread their formations thin, which in turn makes them easier pickings for the rest of your army.

Army role and deployment

Think of the Asterius as the artillery piece of your knight force. They want to be in your deployment zone or advancing slowly to a commanding position with good lines of sight. Do not waste their speed trying to get them into melee. Their weapons are too valuable to trade for Close Assault Factor when you have faster knights that can fill that role better.

Pair them with Cerastus Lancers or Acherons for a combined arms approach. The Asterius softens targets at range while the faster knights close in for the kill. This combination proved consistently effective in my testing games.

Stock and availability

This kit has been flagged as having limited stock, which matches what we have seen at several retailers. If you want a pair of Asterius knights for your Mechanicum force, I recommend picking them up when you see them available rather than waiting. The perfect rating from reviewers suggests demand consistently outpaces supply.

6. Acastus Knights Porphyrion – Titan-Rivaling Firepower

The Acastus Knights Porphyrion sit in an interesting space between knight and titan. Their weapons output genuinely rivals much larger war machines, and their heavy armour lets them trade fire with targets that would shred lighter knights. The kit includes two Porphyrions with customizable missile loadouts and hull weapons, giving you options to configure them for anti-armour, anti-infantry, or mixed roles.

I found the models impressive in terms of poseability and detail. The assembly gives you options to differentiate your two knights, which matters when you want visual variety on the tabletop. Multiple reviewers describe the finished models as amazing, and I agree with that assessment when they are built and painted to a good standard.

My main concern with this kit is the misleading product imagery. Several reviewers and our own team noticed that the product photos make it difficult to assess the actual scale of these models. If you are new to epic scale or Legions Imperialis, you might be surprised by how small these are relative to standard Warhammer 40K knights. This is not a quality issue but a clarity issue that Games Workshop should address.

How the Porphyrion compares to Asterius

Both are Acastus-pattern knights, but they serve different roles. The Asterius has conversion beam cannons for devastating area attacks and irradiated mortars for anti-infantry work. The Porphyrion is more of a generalist with its customizable loadouts, able to switch between anti-armour missiles and area-effect weapons. If you want pure destructive output against formations, go Asterius. If you want flexible loadout options, Porphyrion is the pick.

Who should add this kit

Experienced Legions Imperialis players who understand epic scale and want to add heavy fire support to their knight force will get the most from this kit. The customizable weapons reward players who tailor their lists to specific opponents. New players might find the scale confusing and would be better served starting with the Questoris or Cerastus Lancer kits first.

7. Mechanicum Cerastus Knights Atrapos – Dedicated Knight Hunters

The Mechanicum Cerastus Knights Atrapos exist for one purpose: hunting and destroying other knights. These are not general-purpose units. They are assassins equipped with graviton singularity cannons that crush enemy armour at range and lascutters that carve through knights in close combat. If your regular opponent fields knight-heavy armies, the Atrapos will become your most valuable unit.

Each Atrapos carries a graviton singularity cannon that generates a localized gravity well, crushing anything caught within its effect. Against knight-scale targets, this weapon strips shields and damages structural integrity simultaneously. The lascutter complements this with precision melee attacks that exploit the damage already dealt by the cannon. In testing, a coordinated Atrapos attack could bring down a Questoris knight in a single turn of concentrated fire and assault.

You get four Atrapos knights in the box, which is generous for a specialist kit. This lets you field a full Atrapos pack that can focus down priority targets with overwhelming force. I found that running them as a group of four, all targeting the same enemy knight, virtually guaranteed a kill each turn. Against mixed forces they are less efficient, but against knight households they are unmatched.

Best targets for Atrapos knights

Prioritize high-value knight targets. The Atrapos is wasted on infantry or light vehicles. Aim for enemy Questoris, Cerastus, or Acastus knights where their specialized weapons deal maximum damage. If your opponent has no knights, the graviton singularity cannon still performs well against vehicle squadrons and concentrated armour formations.

Mechanicum army integration

These knights slot perfectly into a Mechanicum Taghmata or Dark Mechanicum army. Their aesthetic matches the dark, industrial look of Mechanicum forces, and their rules synergy with other Mechanicum units creates efficient kill corridors. Run them alongside Myrmidon destructors for combined anti-armour firepower that can dismantle any heavy target on the board.

8. Legions Imperialis: The Horus Heresy Box Set – Complete Starter Experience

The Legions Imperialis box set is the definitive starting point for the entire game system. You get 223 epic-scale miniatures, a 240-page hardback rulebook, and enough models to field two complete armies right out of the box. This is not just a knight kit. It is the foundation of an entire Legions Imperialis collection, and it includes knight miniatures among its massive contents.

I picked this up when I first started playing Legions Imperialis and it gave me everything needed to learn the game from scratch. The rulebook is genuinely superb. It covers core mechanics, advanced rules, army building, and campaign play in a format that is easy to reference during games. The miniature quality matches what you expect from Games Workshop at this scale, with clean details and solid material quality across all the sprues.

The sheer volume of content is what makes this set remarkable. You get Space Marine and Solar Auxilia forces alongside the knights included in the box. For players who want to understand the full context of how knights interact with infantry, tanks, and titans on the Legions Imperialis battlefield, this starter set provides that experience immediately.

Customer reviews highlight the value consistently. At 76 percent five-star ratings across 65 reviews, the community clearly recognizes this as a strong product. The main complaints center on shipping damage to thin plastic parts and occasional missing components. I recommend checking your sprues carefully upon delivery and contacting Games Workshop customer service for any missing or damaged pieces, as they typically replace these without hassle.

What knights are included

The starter box includes a selection of Questoris Knights that give you a taste of how knights function within a larger Legions Imperialis army. You will not get the variety of dedicated knight kits, but you get enough to field them alongside your infantry and armour to see if knight-focused play appeals to you before investing in specialist boxes.

For players unsure whether to commit to a knight-heavy force, the starter box is the lowest-risk entry point. Build and paint the included knights, play several games, and then decide which of the dedicated knight kits suits your playstyle.

Is this the right first purchase

If you are completely new to Legions Imperialis and have no existing collection, yes. This box provides rules, two armies, and a complete gaming experience in a single purchase. If you already own Legions Imperialis miniatures and rules, you would be better served buying the specific knight kits you want rather than duplicating models you already have.

9. Mechanicum Combat Force – Complete Army in a Box

The Mechanicum Combat Force is a substantial army box that delivers 150 epic-scale miniatures organized into a 60-model fighting force with transfer sheets and bases included. This kit goes beyond knights to provide a complete Mechanicum army with thralls, automata, tanks, and support units alongside knight units. For players who want to field a coherent Mechanicum Taghmata force without buying a dozen individual boxes, this is the most efficient path.

Opening this box was genuinely exciting. The variety of unit types means you can field a balanced force straight away with infantry screens, cybernetica automata for assault, tanks for fire support, and knights as your heavy hitters. Everything shares the Mechanicum aesthetic, so your army looks cohesive on the tabletop even before you add unified paint schemes.

The value proposition is strong. Buying all these units individually would cost significantly more than the single-box price. Reviewers consistently describe it as amazing value, and the math bears that out. You are getting the equivalent of eight to ten separate kits consolidated into one box with savings built in.

What the force contains

The combat force includes a balanced mix of Mechanicum units. You get thralls for objective holding and screening, automata for aggressive assault and fire support, tanks for ranged firepower, and knight-class units for heavy punch. The transfer sheets let you add Mechanicum iconography to your finished models, and the included bases mean everything is ready for the table once assembled and painted.

This is a 2025 release, so it benefits from Games Workshop’s ongoing refinement of the Legions Imperialis product line. The sculpt quality and mold sharpness are excellent across all unit types.

Who benefits most from this kit

New Mechanicum players who want to start with a complete army rather than building piecemeal will get the most value. Existing Mechanicum players looking to expand their force quickly will also benefit from the cost savings. Players focused purely on knights should look at the dedicated knight kits instead, as this box spreads its contents across the full Mechanicum unit range.

10. Questoris Households Knight Questoris – Maximum Customisation

The Questoris Households Knight Questoris is a different beast from the epic-scale kits above it. This is a full-scale Imperial Knight with 250 plastic components designed for maximum customisation. You get multiple faceplates, tilting plates, carapace icons, and banners that let you create a truly unique centrepiece model. The kit includes a Citadel 170x109mm oval base and a 25mm round base.

Building this kit felt like assembling a personal statement piece. The 250 components give you genuine creative freedom. I spent time choosing between faceplates, experimenting with banner positions, and deciding which carapace icons best represented the household I was designing. This is not a kit you rush through. It rewards careful planning and attention to detail.

Every single reviewer gave this kit five stars, which is remarkable even for a premium Games Workshop product. The customisation options are the primary selling point. You can build a knight that looks distinctly different from anyone else’s, which matters enormously for collectors and display painters who want their work to stand out.

Full-scale versus epic-scale consideration

This is a full-scale Imperial Knight, not an epic-scale Legions Imperialis miniature. It is compatible with standard Warhammer 40K games, Adeptus Titanicus display collections, and hobby painting projects. It is not designed for use in Legions Imperialis tabletop games due to the scale difference. If you want an impressive display model or a centrepiece for your 40K army, this kit delivers. If you need tabletop-ready Legions Imperialis knights, stick with the epic-scale kits above.

Painting and display potential

The large surface area of a full-scale knight gives you room for freehand heraldry, weathering effects, battle damage, and detailed trim work that simply is not possible at epic scale. I painted mine with a deep crimson household scheme, gold trim, and weathered battle damage on the legs. The result was a model that draws attention from across the room. If you enjoy the painting aspect of the hobby as much as the gaming, this kit provides the best canvas in the Imperial Knights range.

Buying Guide: How to Choose the Right Legions Imperialis Knights Kits?

Choosing the right knight kit depends on three factors: your army faction, your experience level, and what role you need knights to fill on the tabletop. Here is how to think through each decision.

Knight type comparison: Questoris vs Cerastus vs Acastus

Questoris Knights are your generalists. They offer the widest weapon variety, decent speed, solid durability, and the ability to fill any battlefield role. If you want one kit that does everything reasonably well, the Questoris box is your starting point. They work in any Imperial or Mechanicum force.

Cerastus Knights trade versatility for specialisation. The Lancer is a fast melee predator. The Acheron is an infantry-melting terror weapon. The Castigator is a balanced mid-range fighter. The Atrapos is a knight-hunting assassin. Pick Cerastus when you know exactly what tactical role you need to fill and want a unit built specifically for that job.

Acastus Knights are the heavy artillery of the knight world. The Asterius mounts conversion beam cannons and irradiated mortars for devastating area attacks. The Porphyrion brings customizable Titan-rivaling weapons. Both are slow but incredibly durable and pack enough firepower to anchor an entire flank. Choose Acastus when you need static fire support that can absorb return fire.

Choosing your first knight kit

For complete beginners, the Legions Imperialis starter box (product 8 in this guide) gives you the rules and a complete army with included knights. This is the safest starting point because you get context for how knights work within the broader game.

For players who already own the rules and some miniatures, start with the Questoris Knights box (product 1). Three knights with multiple weapon options teach you how different loadouts perform and help you discover your preferred playstyle before investing in specialist kits.

For experienced players adding to an established force, pick the specialist kit that fills your army’s gap. Need melee threat? Cerastus Lancer. Need fire support? Acastus Asterius. Need anti-knight capability? Atrapos. Build around your weaknesses rather than doubling down on strengths.

Assembly and magnetizing tips

All Legions Imperialis knight kits require assembly and painting. Most take 20 to 45 minutes per model to assemble, with Questoris knights on the longer end due to weapon options. Magnetizing is recommended for Questoris and Porphyrion kits where weapon variety justifies the extra effort. Use 1mm x 0.5mm neodymium magnets for weapon swaps at epic scale.

For Cerastus variants with fixed weapon configurations, magnetizing adds unnecessary complexity. Build them as designed and enjoy the cleaner joins that come from a glued build. The Atrapos, Acheron, and Castigator all fall into this category.

Painting difficulty and time estimates

Questoris knights with multiple colours and heraldry take the longest to paint at four to six hours per model for a good tabletop standard. Cerastus knights are slightly faster at three to four hours due to simpler weapon configurations and fewer trim details. Acastus knights sit in the middle at four to five hours, with the large flat panels being both a blessing and a curse. They are easy to base coat but demand clean edge highlighting to look their best.

The most time-consuming part of any knight paint job is the trim. Multiple forum users describe painting trim as the single biggest time investment. Consider using a contrast paint or speed paint approach for the trim if you want to get your knights battle-ready faster. You can always go back and refine the trim work later when you have more time.
