Cost, time and bonus at every level
Harbour Works runs to level 6, adding +1.2% to gather_yield and 95 power each time. Studying it out costs the four soft resources — the same amount of each — and takes 6m 35s 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 |
|---|---|---|---|---|---|
| 1 | +1.2% | 95 | 52s | 3,000 | 50 |
| 2 | +2.4% | 190 | 1m 18s | 4,200 | 70 |
| 3 | +3.6% | 285 | 1m 57s | 5,880 | 98 |
| 4 | +4.8% | 380 | 2m 56s | 8,220 | 137 |
| 5 | +6% | 475 | 4m 23s | 11,520 | 192 |
| 6 | +7.2% | 570 | 6m 35s | 16,140 | 269 |
Taken from nothing to level 6 that is 18m 1s of raw study and 48,960 of each of food, wood, stone and iron — 195,840 resources in total.
Where it sits in the tree
Harbour Works belongs to the Economy branch — the production, construction and gathering line — everything that fills the stores. It stays locked until Foraging Craft reaches level 5 and Deep Mining 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 → Woodcraft to level 5 → Wainwrights to level 5 → Foraging Craft to level 5 → Harbour Works. That is 4 studies standing between a fresh Academy and this one.
