Cost, time and bonus at every level
Smelting runs to level 15, adding +1.2% to gather_yield and 58 power each time. Studying it out costs the four soft resources — the same amount of each — and takes 1h 15m 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 gather yield | Power | Study time | Each resource | Gems to finish instantly |
|---|---|---|---|---|---|
| 1 | +1.2% | 58 | 1m 55s | 12,000 | 2 |
| 2 | +2.4% | 116 | 2m 30s | 15,600 | 3 |
| 3 | +3.6% | 174 | 3m 14s | 20,280 | 4 |
| 4 | +4.8% | 232 | 4m 13s | 26,364 | 5 |
| 5 | +6% | 290 | 5m 28s | 34,273 | 6 |
| 10 | +12% | 580 | 20m 20s | 127,254 | 21 |
| 15 | +18% | 870 | 1h 15m | 472,485 | 76 |
Taken from nothing to level 15 that is 5h 20m 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
Smelting belongs to the Economy branch — the production, construction and gathering line — everything that fills the stores. It stays locked until Quarrying reaches level 5. Studying it opens 1 further tech.
| Tech | Branch | Requires this tech at level |
|---|---|---|
| Deep Mining | Economy | 8 |
The road here: Agriculture to level 5 → Quarrying to level 5 → Smelting. That is 2 studies standing between a fresh Academy and this one.
| Prerequisite | Level required | Each resource | Study time |
|---|---|---|---|
| Agriculture | 5 | 108,517 | 1h 9m |
| Quarrying | 5 | 108,517 | 14m 27s |
| Total before you may begin | — | 217,034 | 1h 23m |
What it eventually opens: 2 studies sit downstream of Smelting, counting every remove.
| Study | Steps out | Buffs | At its cap | Study time at cap |
|---|---|---|---|---|
| Deep Mining | 1 | gather_yield | +14.4% | 34m 21s |
| Harbour Works | 2 | gather_yield | +7.2% | 12m 20s |
