I'm currently in the grace period where I have a "shield" that prevents attacks from other players. When this expires, I assume that I'll start getting attacked. What happens when another player attacks me? I am particularly interested in the following:

  • Do I lose resources? Is it possible to lose them all?
  • Are my buildings destroyed?
  • Do my troops in the Army Camp fight for me, or just stand around?
  • Are their any limits on who can attack me, and how often?
  • How do they decide whether your defense wins or loses?

    what happens if an upgrade or a research was in progress? Jun 18, 2013 at 11:43

    @ArtemOboturov Upgrades and research are not affected by the attack. Once they are started, they will finish after the required wait time.

  • Upgrades are affecting the attacker, in the way that buildings under upgrade is inactive. That is for gold mines, elixir collectors and dark elixir drills, they will not have any resources available to steal (storages will be available though). On the other hand, defensive buildings will not be shooting (but giants and other defense priority troops will target them). Aug 9, 2016 at 11:26

When you are attacked, several things happen:

  • You lose resources, depending on how much the attacker "destroys". If the attacker destroys everything, you can lose up to a maximum of 50% of Elixir/Gold in your collectors, 100% of Elixir/Gold in your Town Hall, and 10-20% of Elixir/Gold in your storage containers depending on your Town Hall level. You also lose 75% of Dark Elixir in your collectors, 5-10% of loot in your Clan Castle and 4-6% of Dark Elixir in your storages This is a worst case, and can be significantly less if the opponent is higher level than you, or does not fully succeed in destroying your buildings.
  • You lose trophies, depending on how much the attacker "destroys" and also the relative amounts of trophies you and the attacker have. Attackers get 1/3 of potential trophies for each star they receive. Potential trophies are more if the attacker started with less trophies than you, and are fewer if the attacker started with more trophies than you.
  • Your buildings are not actually destroyed, even when the opponent "destroys" them. Buildings regenerate after attacks.
  • Troops in your Army Camp do not participate. Troops in your Clan's Castle will fight if any enemy troop is deployed in its radius.
  • There is a range of who can attack you. However, this is based on the number of trophies you have. This makes it possible for high level players to attack you. These players have just simply purposefully lost a bunch of trophies so they can "pick on" low level players. Bear in mind though that pairing is random, so in order for a higher level attacker to attack, they have to be randomly paired with you. Note this does not apply if you've previously attacked them, since they have a "revenge" option.

    "If 40% of your buildings or your townhall are destroyed, you will receive a 12 hour shield." so technically an attacker could get 0 stars, 0 trophies and 0 resources, and you could still get a shield?

    @Celeritas Yes, but your base would have to be specifically designed to allow that to happen :) Jul 27, 2015 at 11:00

    Remember that if you open Clash of Clans while you are being raided, you can watch the battle live. Oct 10, 2015 at 23:16
