The first meadow feels like sanctuary—until the ground shakes or the forest starts moving. A base that survives trolls and greydwarf swarms isn’t built with more walls; it’s built with precise gaps, invisible barriers, and a ditch that confuses pathfinding. This guide lays out the three interlocking systems that turn a starter camp into a fortress, all before you smelt a single bar of iron.
The Raid Threat in the Meadows
The world’s peace is conditional. Once Eikthyr falls, the forest sends boars and necks in a frenzy—more nuisance than danger. After the Elder, the forest truly moves: greydwarf shamans, brutes, and a dozen skulkers pour toward your hearth. Kill a troll and the ground itself trembles, delivering two or more trolls with club arms that erase wooden walls in seconds.
Each raid escalation punishes a single-layer defense. High stakewalls stop greydwarf pebbles but not shaman poison clouds that seep through corners. A solid palisade shatters under a troll’s ground slam if there’s no gap between the wall and the impact zone. Archers—especially starred greydwarves—stand just outside melee range and chip away at structures, their line-of-sight tracing any straight gap.
The solution isn’t thicker walls. It’s three interlocking layers: block enemy sightlines with offset stakewalls, deny spawns entirely with overlapping workbench bubbles, and break pathfinding with a trench so deep that even a troll’s AoE can’t reach across. Together they turn a raid into a delivery of resin, wood, and troll hide.
Stakewall Spacing: Why Gaps Matter More Than Height
A solid line of stakewall panels seems secure, but it invites clustered damage. When a greydwarf swings, its hitbox can clip two adjacent panels if they’re snapped flush. A half-wall gap between panels isolates each strike to a single piece, buying you time during repairs. More importantly, those gaps create a baffle that breaks archer line-of-sight without fully enclosing your base—archers can’t shoot what they can’t see, and a staggered wall forces them to reposition constantly.
Angle the stakewalls inward at roughly 45° on each segment, or build a second, offset inner ring of half-walls and sharp stakes. The outer layer takes the hits; the inner ring blocks vision. A greydwarf shaman that lobs a poison cloud at the outer wall will miss the inner structures entirely if the gap between rings is wide enough—about 2 meters. The result is a base that feels open to you but reads as a solid visual wall to the AI.
Measuring Stakewall Gaps
Use a 1-meter horizontal beam as a spacer. Place a beam on the ground, snap a stakewall panel to one end, then place the next panel on the beam’s far snap point. Remove the beam and you’ll have a precise 1-meter gap. Stand at a greydwarf-equivalent distance and confirm that an arm swing can’t clip through both panels. For extra safety, test with a friend or a tamed creature.
Corner Strategy
Overlap stakewall corners—never leave a sharp 90° joint. A single-panel gap at a corner acts like a funnel for shaman poison clouds and allows brutes to strike two faces at once. Instead, extend one wall past the corner point by a half-panel, then place the perpendicular wall so it overlaps. Finish by snapping a sharp stake to the outermost corner point. It damages anything that presses against the join and discourages enemies from lingering.
Workbench Overlap: The Invisible Barrier
A workbench projects a 20-meter radius sphere of spawn suppression. Enemies cannot appear inside that bubble, but a single bench leaves crescent-shaped dead zones near the edges of a clearing. If your wall sits 15 meters from the bench, anything that spawns just outside can still lob projectiles or rush the gate. The fix is to overlap three to five workbenches so the suppression zone extends 10–15 meters beyond every perimeter wall.
| Coverage Setup | Radius per Bench | Effective Suppression Range Beyond Wall | Typical Benches Needed for 10×10 Base |
|---|---|---|---|
| Single central bench | 20 m | 0–5 m (dead zones at corners) | 1 |
| Three benches in triangle | 20 m each, overlapping | 10–15 m | 3 |
| Five benches in quincunx pattern | 20 m each, overlapping | 15–20 m, full coverage | 5 |
Hiding the benches is critical. If a troll smashes one, spawns can suddenly appear inside your defenses. Bury a bench under a stone pile: raise earth with the hoe, place the bench, then cover it with more stone. Alternatively, sink a core-log support into the ground, snap a floor tile above it, and place the bench on that tile before encasing it in half-walls. The bench remains functional and nearly invisible to raid pathfinding.
Calculating Coverage with Build Pieces
A 4-meter horizontal pole is the perfect measuring tool. Place your central workbench, then equip the pole and walk outward until the bench’s build radius icon fades—that’s 20 meters. Mark that spot. Walk back 4 meters and place a second bench. From that bench, repeat the process, walking perpendicular to form a triangle. For irregular clearings, walk the perimeter with a pole and drop a bench anywhere the suppression circle doesn’t reach the edge of your trench. The goal is no gaps. Deconstruct one bench and check that no greyling or neck spawns within the ring.
Trench Depth: The Troll Test
A troll’s ground slam has a damage radius of about 4 meters from the point of impact. If your wall is within that distance of the trench’s inner edge, the slam transfers through the ground and destroys structures. A trench 6–8 meters deep and at least 4 meters wide puts the far wall well outside that danger zone. A dry trench is safer than a water-filled moat: water lets creatures swim across if they fall in, and the wet debuff slows your own emergency repairs. Dig until the pickaxe’s maximum depth stops you, then use the hoe to raise an earth wall on the base side. That inner cliff should be nearly vertical—a steep slope enemies can’t climb. The outer edge of the trench should be gently sloped, so creatures that wander near the rim slide down instead of getting stuck and piling up. A stuck creature can still attack the trench wall, and a cluster of greydwarves in the ditch will eventually break through.
On the base side, add a stakewall directly atop the raised earth. This serves as a final vision block: even if a troll stands at the trench edge, it can’t see your workbenches or livestock, so it won’t target them. Depth, width, and sight-blocking together make the trench a permanent solution.
Bridge Design
Never build a permanent ramp across the trench. Use core-log beams laid side-by-side as a bridge you can dismantle in seconds when a raid triggers. Alternatively, create a jump-gap bridge: a gap just wide enough that a player can sprint-jump across, but the AI pathfinding refuses to attempt it. A 2-meter gap with a slightly raised lip on the far side usually works. During a raid, simply break the bridge and watch enemies mill about on the far side.
Putting It All Together: A Step-by-Step Defense Layout
- Flatten the land with a hoe, creating a level 10×10 meter footprint.
- Place a central workbench and mark the 20-meter suppression ring with 4-meter poles.
- Dig the trench along that ring, 6–8 meters deep and 4 meters wide, keeping the inner edge vertical.
- Raise an earth wall behind the trench using the hoe and stone. This wall should be at least 2 meters high.
- Place stakewalls on the raised earth, using the 1-meter beam spacer method and overlapping corners.
- Add the inner offset ring of half-walls or sharp stakes 2 meters inside the outer wall.
- Hide additional workbenches along the perimeter, ensuring full coverage beyond the trench.
- Build the bridge as a removable core-log span.
Material checklist for a 10×10 base (approximate):
- Wood: 400–500 (stakewalls, workbenches, inner ring, bridge)
- Stone: 200–300 (raising earth, hiding benches)
- Core wood: 40–60 (bridge, bench supports)
Verification: Deconstruct one perimeter workbench and wait a full day. No creature should spawn inside the ring. Then kite a greydwarf toward the trench and watch its pathing—it should run along the outer edge, unable to find a crossing point.
Upgrading the Defense for Later Biomes
Once stone becomes plentiful, replace stakewalls with stone blocks while keeping the same spacing principles. Stone walls are immune to greydwarf attacks and shrug off all but the heaviest troll swings. Iron gates placed to open outward will swing into the trench when a fuling or seeker presses against them, dumping the attacker. Ballistas on raised earth platforms cover blind spots where the trench curves, thinning waves before they reach the walls. After the Mountains, a section of the trench can become a wolf pit: drop a pair of tamed wolves inside and they’ll breed, creating a self-replenishing defense that shreds anything that falls in.

Conclusion
When the ground shakes, the forest moves, or the horde assaults from the plains, a base built with staggered stakewalls, overlapping spawn suppression, and a deep, dry trench doesn’t just survive—it harvests. Enemies pile up outside, unable to see your benches, unable to path across the gap, and unable to land a meaningful blow. Raids become a resource delivery system, all because of three simple, interlocking systems you can build with meadow-tier materials.
