Hi, I'd like to have some specific information about the Notre Dame wonder, It says reduces costs for library reserc and unit upgrade, and once in a day produces gold. Could someone who has aldready built it tell me something more (with numbers)? Thank you all!

It gives me 5,000 coin. And 10% off research.

It gives 10% discount for your forge troops upgrade and library research. Also gives around 5000 coins once per day which is miniscule.
