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 43m 15s 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 |
|---|---|---|---|---|---|
| 1 | +1.2% | 72 | 30s | 3,000 | 50 |
| 2 | +2.4% | 144 | 45s | 4,200 | 70 |
| 3 | +3.6% | 216 | 1m 8s | 5,880 | 98 |
| 4 | +4.8% | 288 | 1m 41s | 8,220 | 137 |
| 5 | +6% | 360 | 2m 32s | 11,520 | 192 |
| 10 | +12% | 720 | 19m 13s | 61,980 | 1,033 |
| 12 | +14.4% | 864 | 43m 15s | 121,500 | 2,025 |
Taken from nothing to level 12 that is 2h 8m of raw study and 417,660 of each of food, wood, stone and iron — 1,670,640 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 | 32,820 | 26m 23s |
| Logistics | 5 | 32,820 | 30m 47s |
| Statecraft | 8 | 103,140 | 2h 27m |
| Total before you may begin | — | 168,780 | 3h 24m |
What it eventually opens: 4 studies sit downstream of Roadworks, counting every remove.
| Study | Steps out | Buffs | At its cap | Study time at cap |
|---|---|---|---|---|
| Cartography | 1 | march_speed | +12% | 22m 26s |
| Post Riders | 1 | march_speed | +12% | 22m 26s |
| Toll Roads | 1 | production_rate | +12% | 22m 26s |
