Precision Parts Calculator

Everything up to WT30 is a resource problem. Wood, stone, electricity and iron are slow, but they regenerate — you can farm them, buy them, or wait them out. The Industry levels are not like that. Precision Parts cannot be farmed, cannot be bought with resources, and cannot be sped up. They come from daily Radar events and from packs.

So the planning problem flips. Build timers and wood stop being the blocker. The parts are the blocker, and the only question worth asking is where to spend the ones you have.

One Industry level = five building level-ups (five notches). Industry 1 takes a building from Lv.30 to Lv.35, Industry 2 to Lv.40, and so on. The parts cost per notch is fixed within a level, so a full level always costs exactly 5× the per-notch price. The game calls these Industry levels; the tower itself is the Industrial Watchtower, and the same system runs the Industrial Guild and camps.

Three buildings gate every Industrial Watchtower level: the Watchtower itself, the Guild, and one faction camp. The Guild and the camp must be one level below the Watchtower level you are reaching for. Watchtower Industry N needs Guild i(N−1) and one camp at i(N−1).

Which camp rotates on a strict three-level loop, starting with Blastproof Hall (the Fighter camp), then Firearms Vault (Shooter), then Motor Workshop (Rider):

Industry 1 is the free one: buildings at plain Lv.30 satisfy it, and Lv.30 costs no Precision Parts. Every level after that is paid for. These are the names the game uses on the Industry screens — a Watchtower Industry 8 panel reads "Guild Lv.7 Industry · Firearms Vault Lv.7 Industry".

Because each camp is called on only every third Watchtower level, it must climb three Industry levels at once every time its turn comes round — and you pay for all three before the tower can move.

Example: your Blastproof Hall sits at i3 after Watchtower i4. It isn't needed again until Watchtower i7, which wants it at i6. That single step drags Blastproof Hall through i4, i5 and i6 — 2,050 parts — before a single part goes into the tower. A cost chart read row by row hides this completely: it looks like one camp upgrade per level. It is three. The ladder above flags these jumps in red.

Add up every building — the tower, the Guild and all three camps — and the minimum bill from a fresh WT30 is 34,400.

The three camps together cost 15,150 — nearly as much as the Watchtower itself. They are not optional: the rotation calls on all three before Industry 10. They stop at different heights only because the sequence runs out at i10, and Blastproof Hall is last in the loop. The Guild is only 10% of the bill but is needed at every single level, so it can never be put off. Stopping earlier: 24,350 to Industry 8, 28,950 to Industry 9.

It is decided by the rotation, not the camp. Whichever camp unlocks your last level is already being dragged most of the way there, so finishing it costs one level instead of three.

To Industry 10 that makes Blastproof Hall the cheapest main camp (+1,500 over the minimum), Motor Workshop next (+2,600) and Firearms Vault the dearest (+3,400). The answer moves with your target: stop at Industry 8 and Firearms Vault is cheapest; stop at Industry 9 and it is Motor Workshop. Troop strategy should still outrank a difference of two thousand parts — but know it before you commit a faction.

No building can pass the Watchtower's Industry level — a Blastproof Hall at i5 needs a Watchtower at i5. The camp upgrades are what raise troop attack, defence and HP and unlock unit skills. The tower is the key; the camp is the payoff. So the usual play is to raise your main camp every time the tower goes up, and bring the others along later.

Full-level cost (5 notches). Camps are charged the same at a given level whichever camp is climbing. Industry 5 genuinely costs more than Industry 6 on every building — the only place the curve runs backwards. * Industry 9 and 10 come from a community chart and are not yet checked in-game.

Levels 1–8 started from a community chart and were then checked against the game's own Industry panels on 14 Sep 2026: Watchtower i5→i6 at 300 per notch, Watchtower i7→i8 at 350, Blastproof Hall i6→i7 at 140, Firearms Vault i6→i7 at 140, Guild i7→i8 at 100. All five matched.

The camp order — Blastproof Hall, Firearms Vault, Motor Workshop — was read off the game's requirement lines. This page ran it in a different order until 14 Sep 2026; the totals did not change, but which faction is cheapest to carry did. If you planned a faction before then, re-run it.

Industry 9 and 10 come from a community chart by Panikbaby, shared with us by AnnaTheNana ([DoT], #442) — thank you both. Per notch: Watchtower 400 and 450, each camp 220 and 300, Guild 120 and 150. The Watchtower and camp figures match two other community sources, AtlantisHUB and dw.zilo-project.com; the Guild figures are Panikbaby's alone. None of the Industry 9 and 10 costs has been checked in-game yet.

Two sets of costs on this page have not been photographed in-game: the Industry 5 per-notch figure (370), and every Industry 9 and 10 cost. Nobody has confirmed whether Industry 10 is the top level, either. Have a screenshot of any of those panels? Send it.
