Cost, time and bonus at every level
The Long Memory runs to level 5, adding +1.2% to production_rate and 140 power each time. Studying it out costs the four soft resources — the same amount of each — and takes 10m 57s 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% | 140 | 3m 50s | 12,000 | 4 |
| 2 | +2.4% | 280 | 4m 59s | 15,600 | 5 |
| 3 | +3.6% | 420 | 6m 29s | 20,280 | 7 |
| 4 | +4.8% | 560 | 8m 25s | 26,364 | 9 |
| 5 | +6% | 700 | 10m 57s | 34,273 | 11 |
Taken from nothing to level 5 that is 34m 40s of raw study and 108,517 of each of food, wood, stone and iron — 434,068 resources in total.
Where it sits in the tree
The Long Memory belongs to the Dominion branch — the statecraft line — roads, ravens, coin and the reach of your writ. It stays locked until Great Works reaches level 3 and The Unbroken Line reaches level 3 and Concentric Castles reaches level 3 and The Great Council reaches level 3. 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 → Masonry to level 8 → Stonecutting to level 5 → Great Works to level 3 → The Long Memory. That is 5 studies standing between a fresh Academy and this one.
