Infirmary: levels, cost and upgrades

Infirmary takes in severely wounded soldiers instead of losing them, which decides what a lost battle costs. Healing a soldier runs at 30% of recruiting a new one. A research node opens a fourth Infirmary. The building unlocks after Sanctuary level 7 and goes up to level 30. Up to 3 can be built. Levels raise: infirmary Capacity.

Levels and cost

Reference levels of the building: what it gives, how much Might it brings and what the next step costs. Cost grows faster than the payoff: the last five levels take 79% of the total build time.

Level	Infirmary Capacity	Might	Cost	Time
1	677	500	Grain 14, Timber 4	under a minute
5	891	3,400	Grain 19,280, Timber 6,556	10m
10	1,131	7,400	Grain 554,700, Timber 188,200, Herb 151,700	4h 10m
15	1,374	18,900	Grain 5,096,000, Timber 1,699,000, Herb 1,422,000	16h 41m
20	1,639	49,200	Grain 45,300,000, Timber 15,100,000, Herb 12,270,000	3d 17h
25	1,835	119,600	Grain 216,500,000, Timber 70,870,000, Herb 57,220,000	16d 14h
30	2,030	280,500	Grain 1,104,000,000, Timber 361,500,000, Herb 296,900,000	76d 23h

Full upgrade

Taking the building from level 1 to 30 costs Grain 3,870,994,192, Timber 1,282,411,776, Herb 1,043,371,300. Pure build time without speed-ups: 299d 4h, that is, about 10 months.

How to use it

The Infirmary decides what a lost battle costs: healing a soldier runs at 30% of recruiting a new one, and everything that does not fit inside is gone for good. Capacity of one Infirmary grows from 677 to 2,030 places, and of three to 6,090.

It grows unevenly. Level 20 gives 1,639 places for 13 days 6 hours of pure build time, level 30 gives 2,030 for 299 days 4 hours: the last ten levels add 391 places and take 286 days. Three Infirmaries at level 20 gather 4,917 places in under 40 days, four fifths of the top capacity for one percent of the total time.

The Infirmary asks for three times more Grain than Timber: 3,870,994,192 against 1,282,411,776. The Research Lab at the same Sanctuary level 7 takes 4,475,751,165 of each, so Farms and Lumberyards carry uneven loads here.

Level 10 costs 2,411,368 resources and 12 hours and already holds 1,131 places, so the first days after Sanctuary level 7 opens are closed almost for free.

A research node opens a fourth Infirmary, and the same fork applies to it: level 20 comes in a fortnight, while level 30 asks for another 286 days in return for 391 places and 231,300 Might. A finished Infirmary brings 280,500 Might, slightly more than the 280,200 of the Training Grounds, and three of them come to 841,500 between them.
