Accumulating Alliance Special Resources.. or not

[nedlear]

HI,
Just to clarify, if two members of the same alliance both have an alliance-contributing special resource, for example, "Special resource Coal    5% Infantry (swordsmen and spearmen) attack bonus", do both resources go to all members adding 10% or just the one with a maximum of 5%?

I am aware that if a member has both 'special' and 'rich' versions of a resource then it's only the bigger one benefitting that member. I'm also aware that it is only 6 or so that do contribute to the alliance.

As you can see here in this text from the 'how to play' page Iit is not specified.

"Special resources
If you found a province, a colony or a trading post on such terrains, it will give bonus to the whole empire. The bonus is received on condition that the foundation of the object on that terrain is completed. They take up 1 point on the Global map and are located outside the exclusive zone.

* Bonuses of the same Special resource type cannot be accumulated. If there are 2 bonuses of the same type, only the bigger one is accounted. The same bonus granted by two different special resource terrains are accumulated.

Example: If you have 2 holdings on rich gold field, you will have 10% gold income bonus. If you have 1 colony on rich wheat field and 1 on rich rice field, you will have 20% farm effect bonus."

Thank you very much

Hi, nedlear. Only the special resources listed below grant alliance bonus, if an alliance member founds a holding on them. But this bonus applies only to the alliance armies, the special resource conquered by an alliance member will not grant bonus to the Empire of another ally. Only the special resources you've conquered by yourself will grant bonus to your Empire.

Special resources that grant bonuses to the alliance armies:
Ancient Temple, Sacred Ancient Temple,
Horseshoe, Heavy Horseshoe,
Yew, Rich Yew Field,
Coal, Rich Coal Field,
Horses, Heavy Horses,
Wool, Rich Wool Field,
Cotton and Rich Cotton Field.

The same rules as for the personal bonuses apply:  Bonuses of the same Special resource type cannot be accumulated. If there are 2 bonuses of the same type, only the bigger one is accounted. The same bonus granted by two different special resource terrains are accumulated.
Example: If there are 2 holdings on Heavy Horseshoe in the alliance, your alliance army will have 10% bonus to Attack of all Cavalry. If there is one holding on Rich Wool Field and 1 on Rich Cotton Field in the alliance, your alliance army upkeep will be decreased by 20%.
