The Warhammer Age of Sigmar Extremis Starter Set lands on the table like a miniature battlefield in a box, with chunky Stormcast figures and toothy Kruleboyz staring at each other across plastic ruins. You smell acrylic paint, hear dice clatter, and realise this is not a small game night.

What comes in the box

Games Workshop pitched the Extremis Starter Set as the top-tier entry point for the current Age of Sigmar edition, aimed at players who want a full-size experience from day one. Inside you get two playable forces, one of elite Stormcast Eternals and one of swampy Orruk Kruleboyz, plus a fold-out board and a solid collection of ruins-style terrain.

Compared with the smaller Warrior and Harbinger sets, Extremis adds more bodies on the table and more scenery, so a first game already feels like a proper pitched battle rather than a demo skirmish. The terrain pieces are heavy in the hand and click into the baseboard with a satisfying, almost toy-like firmness that helps the battlefield stay tidy during play.

Rules, learning curve and feel

The Extremis box includes a full core rulebook for the current edition plus a smaller getting-started booklet that walks two players through staged missions. You move from basic movement and combat to command points and battle tactics, so the complexity ramps up rather than hitting you at once.

On the table, that structure makes the first two games fast and clear, while the third and fourth start to show the depth that veteran Age of Sigmar players like to talk about. Designer Phil Kelly, a long-time name behind Warhammer rules, has spoken in past interviews about wanting the latest edition to stay sharp and readable even when armies grow large, and Extremis leans into that philosophy.

Miniatures quality and hobby experience

The Stormcast and Kruleboyz in Extremis use modern push-fit designs, so most figures go together without glue. For a new player that means the first regiment really can be ready within an evening, while veterans can still take time to trim mould lines and pose shields for a cleaner finish.

The plastic feels robust and slightly waxy under the knife, as you would expect from recent Games Workshop sprues, and the level of surface detail is high enough that a simple basecoat and wash already makes armour plates and leather straps pop. Reviewers often point out that the sculpts from the Extremis set hold up well even when mixed into larger collections later.

Price point and positioning

Extremis sits at the top of Games Workshop's three-step starter ladder, above the smaller Warrior and mid-range Harbinger sets. That higher price reflects the extra terrain and the thicker rule content, and puts the box in the territory where families may choose it as a main birthday or holiday present rather than an impulse buy.

For existing hobbyists, the value equation is different: you effectively get a rules bundle, terrain and reinforcements for both Stormcast and Kruleboyz in one hit. Many players treat Extremis as a way to refresh their rules and add scenery even if they already own similar units from earlier releases.

Target players and table size

The included board is smaller than a full tournament mat but large enough that both forces can manoeuvre instead of simply rushing straight ahead. That matters if you play on a kitchen table, where space is limited and a standard 6x4-foot battlefield is unrealistic.

Games Workshop makes clear in its marketing that Extremis is designed for two players who plan to continue the hobby beyond the first few games, not just a one-off curiosity purchase. The missions in the booklet encourage upgrades, suggesting how you could expand Stormcast into a more self-assured spearhead or grow Kruleboyz into a wider, swampier horde.

Strengths and weaknesses

One clear strength is how cohesive the contents feel: the terrain, forces and missions are tuned to each other, so you do not spend the first evening leafing through external books. That makes it easier for a parent or friend to run the first game without needing deep system knowledge.

The main drawback is the same one that often follows Games Workshop starter sets: once you dive in, you quickly discover that full armies, extra heroes and larger boards cost real money and time. For some new players the leap from the contained Extremis experience to the broader hobby can feel a little steep.

Company context and share reference

Games Workshop Group PLC builds its business on long-lived systems like Warhammer 40,000 and Age of Sigmar, and starter boxes such as Extremis are a key entry funnel into those ecosystems. The company lists its shares in London under ISIN GB0003718474, and the Games Workshop share price is closely watched by hobbyists-turned-investors who see strong starter set sales as one indicator of future demand.
