Cost, time and bonus at every level
Post Riders runs to level 10, adding +1.2% to march_speed and 76 power each time. Studying it out costs the four soft resources — the same amount of each — and takes 22m 26s 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% | 76 | 35s | 3,000 | 50 |
| 2 | +2.4% | 152 | 53s | 4,200 | 70 |
| 3 | +3.6% | 228 | 1m 19s | 5,880 | 98 |
| 4 | +4.8% | 304 | 1m 58s | 8,220 | 137 |
| 5 | +6% | 380 | 2m 57s | 11,520 | 192 |
| 10 | +12% | 760 | 22m 26s | 61,980 | 1,033 |
Taken from nothing to level 10 that is 1h 6m of raw study and 209,400 of each of food, wood, stone and iron — 837,600 resources in total.
Where it sits in the tree
Post Riders belongs to the Dominion branch — the statecraft line — roads, ravens, coin and the reach of your writ. It stays locked until Roadworks reaches level 5. Nothing further in the tree depends on it, so it is a leaf: worth taking for its own bonus, never as a stepping stone.
The road here: Agriculture to level 5 → Logistics to level 5 → Statecraft to level 8 → Roadworks to level 5 → Post Riders. That is 4 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 |
| Roadworks | 5 | 32,820 | 6m 36s |
| Total before you may begin | — | 201,600 | 3h 31m |
Numerically twinned with Cartography. Same cap, same rate per level, same study time, same power — the figures on those pages match these exactly. What separates them is the flavour and, more usefully, what each one gates: this one opens nothing further, while Cartography opens Scouting Networks. If you only want the bonus, take whichever is cheaper to reach; if you are building toward something, take the one that gates it.
