Cost, time and bonus at every level
Roadworks runs to level 12, adding +1.2% to march_speed and 72 power each time. Studying it out costs the four soft resources — the same amount of each — and takes 34m 21s for the final level alone. Gems are only ever the optional instant finish; the study itself is bought with what your fields already make.
| Level | Total march speed | Power | Study time | Each resource | Gems to finish instantly |
|---|---|---|---|---|---|
| 1 | +1.2% | 72 | 1m 55s | 12,000 | 2 |
| 2 | +2.4% | 144 | 2m 30s | 15,600 | 3 |
| 3 | +3.6% | 216 | 3m 14s | 20,280 | 4 |
| 4 | +4.8% | 288 | 4m 13s | 26,364 | 5 |
| 5 | +6% | 360 | 5m 28s | 34,273 | 6 |
| 10 | +12% | 720 | 20m 20s | 127,254 | 21 |
| 12 | +14.4% | 864 | 34m 21s | 215,059 | 35 |
Taken from nothing to level 12 that is 2h 22m of raw study and 891,923 of each of food, wood, stone and iron — 3,567,692 resources in total. Levels above 10 additionally consume an advanced forging material, one more unit per level past the threshold, so the last 2 levels also need the forge working.
Where it sits in the tree
Roadworks belongs to the Dominion branch — the statecraft line — roads, ravens, coin and the reach of your writ. It stays locked until Statecraft reaches level 8. Studying it opens 3 further techs.
| Tech | Branch | Requires this tech at level |
|---|---|---|
| Cartography | Dominion | 5 |
| Post Riders | Dominion | 5 |
| Toll Roads | Dominion | 8 |
The road here: Agriculture to level 5 → Logistics to level 5 → Statecraft to level 8 → Roadworks. That is 3 studies standing between a fresh Academy and this one.
| Prerequisite | Level required | Each resource | Study time |
|---|---|---|---|
| Agriculture | 5 | 108,517 | 1h 9m |
| Logistics | 5 | 108,517 | 1h 20m |
| Statecraft | 8 | 286,292 | 4h 34m |
| Total before you may begin | — | 503,326 | 7h 4m |
What it eventually opens: 6 studies sit downstream of Roadworks, counting every remove.
| Study | Steps out | Buffs | At its cap | Study time at cap |

| Cartography | 1 | march_speed | +12% | 23m 43s |
