Do the Money Traits Stack ?

[Antearz]

Currently using Wizards to Buff my Economy.
I of course try to get Noblemen for the 10% extra Income.

Now Question is.
Do the Skills and the Traits Stack ?

The Wizard on Empire has a Skill to Increase Income.
And I am using Noblemen Trait.

So if I have 5 Wizards like this. Will all of them give the Full Bonus ?
Will they get a Nerfed Bonus ?
Or will only 1 of them actually give the Bonus ???

Thanks for the Help.

Oh yes. They stack.

Look up “High Elves” and “Entrepreneur” trait.

They do stack, but be mindful. Just because you can stack the income does not mean it's worth it for all Empire factions.
As far as I remember doing some math on it, it took some 10+ mages before it was worth it playing as Karl Franz (using Altdorf as the money maker - at some point Marineburg is better) - simply put in the beginning the wizard upkeep cost simply eats the profit whereas it is immediately profitable for Gelt as he gets a 50% upkeep reduction to wizards.

Same goes for certain % buildings.
Unless you can stack 3 or 4 in a province they are rarely worth it.

Take High Elves as an example.
Their Public order building grants:
60 (T1) - 90 (T2) - 120 (T3) - 180 (T4) - 240 (T5)
They also have another Infrastructure building granting 10% and 30% income from the Public order building.
Their Industry grants
100 - 150 - 200.
So from this one can surmise that:
If there are only 2 Regions in a Province the Entertainment building giving 120 + 240 with only 40% increase grants 504g
Whereas going with Entertainment building + Industry building will net you a lovely amount of 760g

Granted this example takes for granted that the 3 building slot is for walls.

The income stacking buff isn't too useful for that many factions, but for High Elves and Bretonnia it's really good.

For Bretonnia the starting trait Magnanimous that Prophetess's get along with other skills in the Campaign skill tree that increase income all together will give you more income than you lose from the lords upkeep. It's not as powerful as HE but you can technically have unlimited Lords. I managed to get a province making 30k or more as Bretonnia using this trick, you want to combine it with high Chivalry and multiple Cathedrals of the Lady so your lords start off at higher levels so you can get all of the income increasing skills right away.
