Antitoxin Workshop: levels, cost and upgrades

Antitoxin Workshop produces Antitoxin, and at level 30 yields 259,666 an hour, more than any other production building. No storehouse exists for Antitoxin, so an attacker carries off the entire stock. The building unlocks after Sanctuary level 5 and goes up to level 30. Up to 5 can be built. Levels raise: antitoxin Output/Hour, max Production Time.

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	Antitoxin Output/Hour	Max Production Time	Might	Cost	Time
1	1,556	8h 8m	400	Grain 9, Timber 9	under a minute
5	8,095	8h 40m	3,000	Grain 3,555, Timber 3,555	5m
10	21,115	9h 20m	5,800	Grain 62,790, Timber 62,790, Herb 19,150	44m

Full upgrade

Taking the building from level 1 to 30 costs Grain 431,397,577, Timber 431,397,577, Herb 141,063,770. Pure build time without speed-ups: 49d 20h.

How to use it

The Antitoxin Workshop reaches level 30 in 49 days and 21 hours, faster than anything else at Sanctuary level 5, and five of them may stand at once. Five full workshops cost 249 days and 8 hours and 5,019,294,620 resources.

Output climbs from 1,556 an hour at level 1 to 259,666 at level 30. Five workshops together yield 1,298,330 an hour, more than idle income at its best with 1,188,000. Level 20 comes in 2 days and 5 hours and yields 108,372 an hour, forty-two percent of the final rate, so all five are taken to level 20 first: that costs 11 days and 2 hours in total.

Production banks for a limited time: 29,280 seconds at level 1 and 43,200, or 12 hours, at level 30. Five workshops hold 15,579,960 antitoxin, and whatever would pile up beyond that is lost. Sanctuary level 5 grants five slots of the same kind to the Smelting Workshop and the Weaving Workshop as well, yet each of those needs 99 days and 17 hours against the 49 days and 21 hours here.

Collecting the haul matters for a second reason: no storehouse exists for antitoxin, so a full bank goes to a raider whole. For comparison, stage 10 of the Undead Siege pays out 255,600,000 antitoxin, 197 hours of work for five workshops.
