Cost, time and bonus at every level
Drilling runs to level 20, adding +2.5% to train_speed and 80 power each time. Studying it out costs the four soft resources — the same amount of each — and takes 3d 20h 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 train speed | Power | Study time | Each resource | Gems to finish |
|---|---|---|---|---|---|
| 1 | +2.5% | 80 | 2m 30s | 3,000 | 50 |
| 2 | +5% | 160 | 3m 45s | 4,200 | 70 |
| 3 | +7.5% | 240 | 5m 38s | 5,880 | 98 |
| 4 | +10% | 320 | 8m 26s | 8,220 | 137 |
| 5 | +12.5% | 400 | 12m 39s | 11,520 | 192 |
| 10 | +25% | 800 | 1h 36m | 61,980 | 1,033 |
| 15 | +37.5% | 1,200 | 12h 9m | 333,360 | 5,556 |
| 20 | +50% | 1,600 | 3d 20h | 1,792,920 | 29,882 |
Taken from nothing to level 20 that is 11d 13h of raw study and 6,267,660 of each of food, wood, stone and iron — 25,070,640 resources in total. Levels above 10 additionally consume an advanced forging material, one more unit per level past the threshold, so the last 10 levels also need the forge working.
Where it sits in the tree
Drilling belongs to the Military branch — the offence line — what your swords, horses and bows hit for. It stays locked until Armor reaches level 5. Studying it opens 4 further techs.
| Tech | Branch | Requires this tech at level |
|---|---|---|
| Infantry Discipline | Military | 5 |
| Horsemanship | Military | 5 |
| Muster Rolls | Military | 8 |
| Statecraft | Dominion | 5 |
The road here: Weaponry to level 3 → Armor to level 5 → Drilling. That is 2 studies standing between a fresh Academy and this one.
| Prerequisite | Level required | Each resource | Study time |
|---|---|---|---|
| Weaponry | 3 | 13,080 | 12m 40s |
| Armor | 5 | 32,820 | 35m 10s |
| Total before you may begin | — | 45,900 | 47m 50s |
What it eventually opens: 21 studies sit downstream of Drilling, counting every remove.
