Cost, time and bonus at every level
Infantry Discipline runs to level 10, adding +1.2% to defense and 72 power each time. Studying it out costs the four soft resources — the same amount of each — and takes 20m 20s 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 instantly |
|---|---|---|---|---|---|
| 1 | +1.2% | 72 | 1m 55s | 12,000 | 2 |
| 2 | +2.4% | 144 | 2m 30s | 15,600 | 3 |
| 3 | +3.6% | 216 | 3m 14s | 20,280 | 4 |
| 4 | +4.8% | 288 | 4m 13s | 26,364 | 5 |
| 5 | +6% | 360 | 5m 28s | 34,273 | 6 |
| 10 | +12% | 720 | 20m 20s | 127,254 | 21 |
Taken from nothing to level 10 that is 1h 21m of raw study and 511,434 of each of food, wood, stone and iron — 2,045,736 resources in total.
