Cost, time and bonus at every level
The Unbroken Line runs to level 6, adding +1.2% to defense and 100 power each time. Studying it out costs the four soft resources — the same amount of each — and takes 6m 58s 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 defense | Power | Study time | Each resource | Gems to finish |
|---|---|---|---|---|---|
| 1 | +1.2% | 100 | 55s | 3,000 | 50 |
| 2 | +2.4% | 200 | 1m 23s | 4,200 | 70 |
| 3 | +3.6% | 300 | 2m 4s | 5,880 | 98 |
| 4 | +4.8% | 400 | 3m 6s | 8,220 | 137 |
| 5 | +6% | 500 | 4m 38s | 11,520 | 192 |
| 6 | +7.2% | 600 | 6m 58s | 16,140 | 269 |
Taken from nothing to level 6 that is 19m 4s 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
