Alliance bonuses allow alliance members to collectively improve important game mechanics by donating resources. Once unlocked, bonuses apply to all alliance members, with some limitations for newly joined players. This article explains how alliance bonuses work, what effects they provide, how to unlock them, and which exceptions apply.
Alliances can unlock four different bonuses. Each bonus has five levels, and higher levels increase the effect of that bonus.
The available alliance bonuses are:
Increases troop production speed in all troop-producing buildings
Increases Culture Point (CP) production
CP is generated by buildings and hero helmets
Town Hall celebrations are not affected, except on specific special servers
Increases troop offensive and defensive strength
This bonus is applied on top of existing smithy upgrades
Increases merchant carrying capacity
On some special servers, alliance bonuses behave differently.
Philosophy bonus also affects Town Hall celebrations and artworks
The CP limit from these sources is increased
Commerce bonus increases merchant speed in addition to carrying capacity
Each bonus increases gradually with its level. The effects are identical across all four bonus types.
LevelEffect | |
0 | No bonus |
1 | +2% / +4% |
2 | +4% / +8% |
3 | +6% / +12% |
4 | +8% / +16% |
5 (max) | +10% / +20% |
(The exact percentage depends on the bonus type.)
Alliance bonuses are unlocked through resource donations from alliance members.
Key rules:
Each bonus level requires a higher total amount of resources
All four bonuses have the same resource requirements and upgrade times
Resource type does not matter; only the total amount donated is counted
Resources cannot be donated while a level is actively unlocking
Once the required amount is reached, the upgrade countdown begins automatically.
Level | Upgrade Time* | Required Donations | Daily Donation Limit* |
1 | 24 hours | 1,200,000 | 300,000 |
2 | 48 hours | 5,600,000 | 400,000 |
3 | 72 hours | 17,100,000 | 550,000 |
4 | 96 hours | 51,200,000 | 750,000 |
5 | 120 hours | 153,600,000 | 1,000,000 |
* Upgrade time and donation limits are adjusted by server speed.
Each player has a daily donation limit
The limit depends on the highest bonus level currently unlocked in the alliance
Donation limits cannot be exceeded
For 3 Gold, players can triple a donation (e.g. 10,000 counts as 30,000), but this still cannot exceed the daily donation limit.
Some alliance bonuses are multiplied with other effects:
Recruitment bonus is multiplied with hero items (e.g. Helmet of the Mercenary)
Metallurgy bonus is multiplied with smithy upgrades
Commerce bonus is multiplied with the Trade Office
Gaul merchant base capacity: 750
Level 4 Commerce bonus (120%): 750 × 2.2 = 1,650
Level 20 Trade Office (400%): 750 × 5 = 3,750
Combined effect: 750 × 2.2 × 5 = 8,250
Alliance contributions are part of daily quests.
While the last alliance bonus is unlocking, the daily quest cannot be completed
Once all alliance bonuses finish activating, the daily quest is automatically marked as completed for all alliance members each day
Alliance bonuses are not fully available immediately to new members.
