Cost, time and bonus at every level
Armor runs to level 20, adding +2% to defense and 90 power each time. Studying it out costs the four soft resources — the same amount of each — and takes 1d 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 | +2% | 90 | 10m 13s | 12,000 | 11 |
| 2 | +4% | 180 | 13m 17s | 15,600 | 14 |
| 3 | +6% | 270 | 17m 17s | 20,280 | 18 |
| 4 | +8% | 360 | 22m 27s | 26,364 | 23 |
| 5 | +10% | 450 | 29m 12s | 34,273 | 30 |
| 10 | +20% | 900 | 1h 48m | 127,254 | 109 |
| 15 | +30% | 1,350 | 6h 42m | 472,485 | 403 |
| 20 | +40% | 1,800 | 1d | 1,754,304 | 1,495 |
Taken from nothing to level 20 that is 4d 11h of raw study and 7,561,985 of each of food, wood, stone and iron — 30,247,940 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
Armor belongs to the Military branch — the offence line — what your swords, horses and bows hit for. It stays locked until Weaponry reaches level 3. Studying it opens 4 further techs.
| Tech | Branch | Requires this tech at level |
|---|---|---|
| Drilling | Military | 5 |
| Shieldwork | Military | 8 |
| Tempering | Military | 10 |
| Fortification | Defense | 8 |
The road here: Weaponry to level 3 → Armor. That is 1 study standing between a fresh Academy and this one.
| Prerequisite | Level required | Each resource | Study time |
|---|---|---|---|
| Weaponry | 3 | 47,880 | 40m 47s |
| Total before you may begin | — | 47,880 | 40m 47s |
What it eventually opens: 51 studies sit downstream of Armor, counting every remove.
