Decorations

Q:
How do decorations work in terms of quantity/bonus/uses info that it displays?

For example: adding a 4th Rustic Lamp provides Bonus 3 again (1% + 1.5% + 3% + 3% = 8.5%), but why doesn't a 5th add anything or how do you know what the 'Max' quantity is? What is 'uses' number?

A:
The uses are how many you can place to get that bonus percentage, then once you've placed that many it'll move to Bonus 2 and then Bonus 3. After you've use all the uses you won't get any more bonuses from that decoration. It counts separately for each building, so you could put 4 lamps next to each building and get 8.5% on each.

So with your lamp example, Bonus 1 and Bonus 2 only have 1 use so you got those bonuses once. Bonus 3 has 2 uses so you got the 3% bonus twice. After that, there are no uses left so you get nothing more and see 'MAX' message. __NOTITLE__
