Cost, time and bonus at every level
Granaries runs to level 15, adding +1.2% to production_rate and 55 power each time. Studying it out costs the four soft resources — the same amount of each — and takes 1h 2m 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 production rate | Power | Study time | Each resource | Gems to finish instantly |
|---|---|---|---|---|---|
| 1 | +1.2% | 55 | 1m 36s | 12,000 | 2 |
| 2 | +2.4% | 110 | 2m 5s | 15,600 | 3 |
| 3 | +3.6% | 165 | 2m 42s | 20,280 | 3 |
| 4 | +4.8% | 220 | 3m 31s | 26,364 | 4 |
| 5 | +6% | 275 | 4m 34s | 34,273 | 5 |
| 10 | +12% | 550 | 16m 56s | 127,254 | 17 |
| 15 | +18% | 825 | 1h 2m | 472,485 | 63 |
Taken from nothing to level 15 that is 4h 27m of raw study and 2,007,435 of each of food, wood, stone and iron — 8,029,740 resources in total. Levels above 10 additionally consume an advanced forging material, one more unit per level past the threshold, so the last 5 levels also need the forge working.
Where it sits in the tree
Granaries belongs to the Economy branch — the production, construction and gathering line — everything that fills the stores. It stays locked until Agriculture reaches level 10. Studying it opens 2 further techs.
| Tech | Branch | Requires this tech at level |
|---|---|---|
| Millwork | Economy | 5 |
| Animal Husbandry | Economy | 5 |
The road here: Agriculture to level 10 → Granaries. That is 1 study standing between a fresh Academy and this one.
| Prerequisite | Level required | Each resource | Study time |
|---|---|---|---|
| Agriculture | 10 | 511,434 | 5h 26m |
| Total before you may begin | — | 511,434 | 5h 26m |
What it eventually opens: 3 studies sit downstream of Granaries, counting every remove.
| Study | Steps out | Buffs | At its cap | Study time at cap |
|---|---|---|---|---|
| Animal Husbandry | 1 | production_rate | +12% | 34m 21s |
| Millwork | 1 | production_rate | +14.4% | 34m 21s |
| Granary Networks | 2 | production_rate | +6% | 11m 52s |
Numerically twinned with Irrigation. 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 Millwork and Animal Husbandry, while Irrigation opens Crop Rotation. If you only want the bonus, take whichever is cheaper to reach; if you are building toward something, take the one that gates it.
