Why is this person attacking me?

For the same reason a dog licks his privates... Because they can!

To continue the "dog analogy", you are a lot like a little terrier who eats out of his food dish every day, and all of a sudden this big, nasty dog comes along and eats all the food in your dish! If you cower under the bed, you remain safe, but if you come out and try and defend your doggie dish, you get savaged! Either way, your food gets eaten.

No worries, your master has most of your dog food in the cabinet, and the big, nasty dog can't get into the cabinet to get the food. You master will get the food out for you any time you want to.

The cabinet is your Storehouse, and the dog dish is everything outside the Storehouse. So it behooves you to have the biggest "cabinet" you can. One of the first things you should concentrate on when you are building your city (especially for the first week of safety you get when you first begin to play KoC).

Your storehouse can store 100,000 of each resource (Food, Wood, Store and Ore) per level. It will not store your Gold. Gold will always be vulnerable. 10,000 is automatically protected by your castle, no matter what level it is (Castle doesn't protect gold, either).

The second thing you should concentrate on is having your alchemist research as high a level of Shrinking Powder as you can. Shrinking Powder increases the capacity of your Storehouse and Castle by 10% for each level of Shrinking Powder you have. Max protection without DIs is 1.729 million of each resource (with level 9 storehouse and level 9 shrinking powder).

While you are doing this, watch out for having too many resources lying around to be picked up. Anything outside your storehouse is fair game. Anything inside your Storehouse is safe from plunder. By the same token, everything outside is not.

So the key to not being attacked, is leave little (or no) plunder lying around. Also, do like the little pooch and hide under the bed when the big, mean dog comes sniffing around your dish.

Let's go to the next section: Keeping plunder low (empty the dog dish)
