You add it up? Not really sure what type question is. It adds to your raw stats at face value, unless it's a percentage bonus. The ones with a percentage lose effectiveness as your troops/spies are depleted. Against EBs the average damage stays the same, but you will be prone to fails if your other equipment doesn't cover the minimum needed to hit.
As far as pro packs, on Android you can only buy them with nobility. So you have to buy the nobility from the Oracle first, then go back to the marketplace and get the pro pack.
Guilds are better until you can buy volaries efficiently for stats if that is what you want. Only the devs know that.
@ laser-kitty: No, an all guild (lvl4) spy build has not higher plunder than an all SoS (lvl3) build, at around land 37. An all guild build however is extremely cheap to get, compared to an all SoS build (even better a volary/SoS build). It permits you to get to 50 lands as fast as possible. Afterwards, you are however advised to save a huge amount of gold to convert most of those guilds to SoS and volaries at once, as replacing guilds one by one has a terrible impact on plunder. A mixed spy build with few SoS and mostly guilds earns less plunder than a full guild build. Once you however have only few guilds vs mostly SoS and volaries, the full guild build would earn less.
one more here. Does uograding your castle add to your actual kcs on your profile for everyone to see? Or is it a bonus more like equipment, that only you can see? Thanks in advance
so even if a person has no spy buildings and no defensive spy buildings they can still have kcs in those? Sorry if this is noobie haha
