CDB - The City Defence Bonus

As questions have resurfaced lately in regard to the CDB (City Defence Bonus) value, here's a quick reminder, or primer for newer players:

The CDB is displayed on the left-hand side of the toolbar top centre:

It shows a value which expresses which additional defensive bonus units defending the city outside the Acropolis will receive: 100 CDB points add 1% defence:

Defensive bonus in % = (CDB / 100) / 100

In the above screenshot, for example, this would add up to:

+141,69% = (14.169 / 100) / 100


An additional +150% defensive bonus is nothing to sneer at, though it will take some time and more than a few Drachmas to get there, but it can be done. Below you'll find a table with all fortifications, buildings, decor and other elements which are able to contribute to the CDB:

Note that the maximum total shown above can be improved with special city schemes and decor and that it does make a slight difference if one is playing on a plarium.com or Facebook server.

This forum thread also discusses city scheme bonuses and CDB values in general.

Cheers

Very rarely LOL  I have seen some CDF much higher than this as well.  Those St. Patricks day decor came in handy but at a price

One of the few extras I invested in, don't really recall why. Guess it was St. Patrick's Day so I was less than sober. 

Anyone remember how much CDB they had assigned?

The one that costs 170 gives 17 CDB, the one that costs 300 - 33 CDB. If I remember correctly, Leprechaun gives 33, other 2 - 17.

Maxed with leprechauns only? Spine-chilling. I am now officially scared. Sounds like a dream I once had :-). 

Plarium recently asked regarding suggestions for new units. Besides a PA, we definitely need a PF, a Potato Famine.

Are you asking how much CDB this decor contributes? If, so please see Alyona's above post:

The one that costs 170 gives 17 CDB, the one that costs 300 - 33 CDB. If I remember correctly, Leprechaun gives 33, other 2 - 17.

If not, hat prcisely do you mean by "combination"?

Soooo ... if someone has a city def value of say 500 ... their C.D.V. will be what exactly?


will that lower the troops defense value in their city ?

the math and the % value is confusing

Every CDB point = 0.01% added to troops defending the city; A CDB of 500 then would add 5% to all defending troops.
