Hello,

I have the 30/30 points in construction cost with Hero Skill which would give 10% of reduction cost but it dosen't give 10%, it only give like 9%


With no reduction in construction cost

Farm/Mine/Stone Quarry/... lvl 18 to 19 required 390.000 of 3 ressources

With 30/30 points in construction cost with Hero Skill = 10%

Farm/Mine/Stone Quarry/... lvl 18 to 19 required 354.000 of 3 ressources


390.000 * 0,9 = 351.000 and not 354.000


I know that ressource cost are not 354.000 but more like 354.545 or something but even if you take 390.999 instead of 390.000 

390.999 * 0,9 = 351.899 still not 354.000 or 354.545


I have no city skin, no daily bonus or kingdom fight bonus


I know it's not big difference but this game is all about 1% more of something

May be i'm wrong, may be i forgot something in this case sorry for the mistake.

You are applying the bonus incorrectly by subtracting it from 100% and then multiplying.

The way you're doing it, if you had a 200% boost, you'd end up with more resources than before you started. :)


The correct formula is (where x is the boost(s) to be applied): Original Amount multiplied by 100%/(100%+x).

SO: a 10% reduction bonus would be

390,000 x 100/110 = 354,545.4545..
