D&D Onslaught Ancient Construct Expansion: Units, Rules, and How It Changes Play

Quick answer

The Ancient Construct expansion adds a durable, construct-focused warband to D&D Onslaught, trading speed for staying power and board control. If you already own a core set and want a faction that plays differently from typical humanoid warbands, this is a strong pickup. If you prefer fast, aggressive lists, other expansions may suit you better.

D&D Onslaught expansions each bring a distinct playstyle to the table, and the Ancient Construct is no exception. This comparison breaks down what the expansion includes, how its units function, and how its rules change the flow of a match. You will also see how it stacks up against other warband options so you can decide if it belongs in your collection.

We will look at the Ancient Construct's contents, its new units, and the scenarios it introduces. Then we will compare it directly to a typical Onslaught warband and to the Nolzur's Marvelous Miniatures line for players who want to mix in additional figures. The goal is to give you a clear picture of the trade-offs before you buy.

What's in the Ancient Construct Expansion

The Ancient Construct expansion for D&D Onslaught includes a set of pre-assembled, pre-painted miniatures, stat cards, and scenario rules. While exact contents can vary by retailer, the core offering is a self-contained warband ready to play out of the box. You get the units, their abilities, and any tokens or markers needed for the included scenarios.

Unlike the Nolzur's Marvelous Miniatures line, which comes primed and ready to paint but requires assembly and painting, Onslaught miniatures are designed for immediate tabletop use. That makes the Ancient Construct a convenient choice if you want to expand your game without a hobby project. The trade-off is that you cannot customize the paint job without stripping and repainting.

• Check the product listing for the exact number of miniatures and cards, as some expansions include bonus items.
• If you already own the Onslaught core set, you only need the expansion to add this warband.

New Units and How They Play

The Ancient Construct warband focuses on resilient, construct-type units that can absorb damage and control key areas of the battlefield. Their abilities often involve repairing or reinforcing each other, making them a grindier force than typical aggressive warbands. You will find yourself playing for attrition rather than quick kills.

In contrast, a standard Onslaught warband might rely on mobility and burst damage. The Ancient Construct trades that speed for durability, which can be a disadvantage in scenarios that require rapid objective grabbing. However, in prolonged fights, their staying power can overwhelm opponents who run out of resources.

• Pair the Ancient Construct with support units that can heal or buff to maximize their resilience.
• Use them to hold chokepoints and objectives while faster units flank.

Rules and Scenarios That Change Play

The expansion introduces scenario rules that emphasize construct synergies and environmental hazards. These scenarios often reward players who can position their units to take advantage of cover and repair mechanics. If you enjoy tactical puzzles over straight combat, these scenarios add a fresh layer to Onslaught.

Compared to the core set scenarios, which are more general, the Ancient Construct scenarios are tailored to the warband's strengths. That means they may not play as well with other factions unless you adapt them. The trade-off is a more thematic experience at the cost of universal usability.

• Read the scenario rules carefully before your first game; some introduce new terrain or objective types.
• You can mix these scenarios with other warbands, but expect some imbalance.

How It Compares to Other Warband Options

If you are choosing between the Ancient Construct and another Onslaught expansion, consider your preferred playstyle. The Ancient Construct is ideal for defensive, control-oriented players. Other expansions might offer faster, more aggressive units or different synergies. There is no single best choice; it depends on how you like to play.

For players who also enjoy painting, the Nolzur's Marvelous Miniatures line offers a different kind of expansion. For example, the D&D Nolzur's Marvelous Miniatures: Aasimar Male Paladin is a highly detailed, primed miniature that you can paint to match your warband. It does not come with Onslaught stat cards, so you would need to use it as a proxy or for RPGs.

• If you want ready-to-play, go with the Ancient Construct expansion.
• If you want to customize your force with unique paint jobs, consider Nolzur's miniatures as alternatives.

Trade-offs to weigh

• Ready-to-play vs. customizable: The Ancient Construct expansion comes pre-painted and ready to play, while Nolzur's miniatures require painting but offer full customization. Choose based on whether you value convenience or hobby time.
• Defensive vs. aggressive playstyle: Ancient Construct units favor resilience and board control, while many other warbands focus on speed and burst damage. Pick the warband that matches your preferred tactics.
• Scenario specificity vs. universal use: The expansion's scenarios are tailored to its units and may not balance well with other factions, unlike core scenarios. If you want to use scenarios across factions, stick with the core set.

Product facts

• D&D Nolzur's Marvelous Miniatures: Aasimar Male Paladin: Comes with a highly detailed figure, primed and ready to paint out of the box, with deep cuts for easier painting. If you want to add a unique, customizable hero to your Onslaught warband, this miniature can serve as a proxy or a painting project, though it lacks official stat cards.
• D&D Nolzur's Marvelous Miniatures: Harengon Rogues: Features highly detailed figures, primed and ready to paint, with deep cuts for easier painting. These rogues can be used as alternative models for Onslaught units if you prefer a different look, but you will need to adapt their rules or use them for RPGs.
• Starfinder Deep Cuts Wave 15 Bundle: Includes five Starfinder Deep Cuts miniatures: Human Mechanic, Kasatha Operative, Shirren Technomancer, Vesk Soldier, and Skittermander Envoy. This bundle offers a variety of sci-fi miniatures that could be used as proxies in Onslaught if you want a different aesthetic, but they are not official Onslaught units.

Who should buy the Ancient Construct expansion?

Best for

• Players who already own the D&D Onslaught core set and want a durable, control-oriented warband.
• Fans of construct-themed armies who enjoy attrition and tactical positioning.

Not for

• Players who prefer fast, aggressive warbands that win through mobility and burst damage.
• Those who want to customize every miniature's paint job without extra work.

The Ancient Construct expansion offers a distinct, defensive playstyle that can breathe new life into your D&D Onslaught games. If its trade-offs align with your preferences, it is a worthy addition. Otherwise, consider other expansions or Nolzur's miniatures for a different experience.
