Look under the strategy section of forums. There's lots of stickied guides there. You can look through them whenever you need that kind of help.
@unknown- attacking is a button you press on a players profile to use your own troops to try to defeat theirs. If u win you earn gold and your target loses a higher percentage of troops than you do. But if you lose, you lose a higher percentage of troops and earn no money. A clan is a group of players following the same basic morales. When u join a clan, you have access to their clan chat to talk to other members. You can only fight estoc wars, system wars and ebs from your clan.
@ midnight- Osw is an abbreviation of off system war. This where 1(or more) clans fights 1(or more) clans out of the system. There's no magical button or whatever for it. Osf stands for open spy farm/ open secret farm. They're basically players that dedicate themselves to being open for hits for friends/clan members. Normally pure spy. I've never heard of OSA :?
Farming is just attacking 5 times or more within a 24hr period. "The defender used 13 pots" is exactly what it says. The person you're attacking has 13 defense pots. Pots are found in the marketplace. Defense pots are used automatically when defending a strike, and they're only a one time use item.
