Alliance Hall: levels, cost and upgrades

Alliance Hall collects Alliance Help, where every ally who responds shaves a few seconds off a queue. The hall's level raises both the number of helps and the weight of each one. Help applies only to building, research and healing queues. The building unlocks after Sanctuary level 5 and goes up to level 30. Only one can be built. Levels raise: alliance Help Count, alliance Help Duration.

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	Alliance Help Count	Alliance Help Duration	Might	Cost	Time
1	4	under a minute	500	Grain 89, Timber 29	under a minute
5	7	under a minute	3,400	Grain 20,840, Timber 7,087	10m

Full upgrade

Taking the building from level 1 to 30 costs Grain 2,569,804,162, Timber 852,399,582, Herb 822,960,900. Pure build time without speed-ups: 199d 10h, that is, about 7 months.

How to use it

The Alliance Hall asks for 199 days and 10 hours, a hundred days less than Squad 4 demands at the same Sanctuary level 5. Help grows through two figures at once: 4 helps of 30 seconds at level 1 come to 2 minutes off a queue, 20 helps of 59 seconds at level 30 to 19 minutes 40 seconds.

Most of that gain comes cheaply. Level 20 is taken in 8 days and 20 hours and gives 15 helps of 49 seconds, 12 minutes 15 seconds off a queue, nearly two thirds of the full 19 minutes 40 seconds. The remaining 7 minutes 25 seconds cost 190 days 14 hours. Alliance research adds up to 300 seconds per help, and twenty of them then take nearly two hours off a queue.

Only building, research and healing accept help, though they accept it daily on every queue. The Builder's Hut has a longer free window at 30 minutes, though it fires only on upgrades shorter than itself, while 19 minutes 40 seconds come off any queue.

The hall's bill leans towards Grain: 2,569,804,162 against 852,399,582 Timber. It carries 235,100 Might. Up to level 20 the hall goes up early, for its 12 minutes 15 seconds and 42,200 Might, and the top ten levels drop to the end of the queue: nothing else buys back 190 days 14 hours for seven minutes.
