Storehouse

The storehouse is where Clan Citadel resources are stored during the build tick. All citadels start with a tier 1 storehouse. Upgrading the storehouse both increases the individual resource cap of every player, so that they can gather more items per build tick, and increases the amount of resources that are carried over to the next build cycle.

Individual resource cap

Every player has a resource cap, limiting the amount of resource that they can gather in the citadel. The resource cap applies to all resources, not to each individually - a player could use their entire resource cap gathering timber, or they could use it making charcoal, then mining some ore and making bars. This ensures that if a clan wants their citadel to reach its very best that all the members work together. The resource cap is reset every build tick. Summoning minions can only use up 10% of your resource cap per week.

The resource cap is increased by upgrading the storehouse:

Storehouse tier	Resource cap
1	1,000
2	1,200
3	1,400
4	1,700
5	2,000
6	2,350
7	2,700

While in the citadel the current resource cap, and amount currently used, is displayed at the bottom of the citadel information screen.

Citadel Resource Storage

When the build tick occurs, most resources that are excess will spoil and be lost. The amount that is carried forward is the excess multiplied by the percentage of that citadel (see below), up to the maximum capacity of that tier of storehouse.

Storehouse Tier	Percentage Carried Over	Timber, Stone, Cloth and Rations Stored	Metal bars and Precious bars Stored	Charcoal, Ore, Precious ore, and Minions Stored	Minimum surplus for maximum carry-over
1	5%	1,000	333	0	20,000
2	10%	1,200	400	0	12,000
3	15%	1,500	500	0	10,000
4	20%	1,800	600	0	9,000
5	25%	2,100	700	0	8,400
6	30%	2,500	833	0	8,334
7	50%	3,000	1,000	0	6,000

For example, if a clan has a tier 1 storehouse (maximum capacity of 1,000) and they have 10,000 surplus wood, they keep the lower of 1,000 or (5% of 10,000) 500 wood. Similarly, if a clan has a tier 7 storehouse (maximum capacity of 3,000) and they have 10,000 surplus wood, they are only able to keep 3,000 despite 50% of 10,000 being 5,000.
