Each epic two-day war is won by the clan who scores more stars! Bonus loot is your prize for winning the war. Increase the bonus by winning attacks, but you will lose most of it if your clan loses the war!
During Preparation Day, War Bases are open for troop donation and can be redesigned using all the parts of your regular Village. These bases defend for you during war and will keep your resources and trophies perfectly safe.
Everyone eligible for war can attack twice during Battle Day. Each participant will have a recommended base (based upon the relative strengths of your army and their defenses), but you can attack any base you like. You must attack two separate bases with your two attacks, however; you are not allowed to attack the same base twice.
Multiple Attacks on the Same Base
Only the best attack against each enemy counts, so clan strategy is key! If two players attack the same enemy base and one person gets one star and the other gets two, the clan only receives two stars (not three). This is to prevent everyone from attacking the easiest enemy bases.
War win bonus
The game calculates and displays a war win bonus unique to every base. The bonus displayed is the loot you will receive if you get at least 1 star and your clan wins the war. You still get the loot even if the base was previously 3-starred.
You might notice that the war win bonus shown to you is not the same as your friends see for the same base. Much like how raid loot suffers a TH penalty, so do War win bonuses. (A base 1 TH lower only offers 90% of its otherwise available War win bonus. 3 TH lower get 12.5%.) The penalty is already calculated into the number you are shown, but awareness of the penalty will help you decide when to upgrade your townhall. Upgrading prematurely will make it harder to make a profit from wars.
At the end of the war, bonus loot is delivered to your Clan Castle. You can review results and battle replays after the war is over, for a period of time. Check your clan's War Log to review even older wars!
For a Victory you would earn the full War Win bonus, which is 6 times the available loot from the bases you successfully attacked. For a Draw you would earn 40% of the war win bonus, and for a Defeat you would earn only 30% of the war win bonus.
- As of the Halloween 2014 update, bonus loot was increased. The war win bonus used to be 5x the loot you could get from the base (e.g. you would win 250k Gold and Elixir if you beat a base containing 50k Gold and Elixir) and losing the war would award you with only 20% of the war win bonus.
- The same update increased the Clan Castle's capacity to store war loot.
