Clash of Clans – Duration of Shield in Clash of Clans: Guide and Tips

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.

It is a bit weird at first - the destruction of your base only yields a hunk of your resources being stolen. Repairing your base takes only a few seconds and costs very little.

The overall goal in the game is pretty murky. There are ever-increasing base upgrade goals to be met, which you will gain either by waiting for your own resources to collect, or more quickly by raiding other people's bases. Pride in your town's strength and building levels could thus be considered a major goal of the game.

However, I would argue that the overall goal is to rank highly in the player-vs-player leagues, which require you to amass tons of trophies by successfully attacking other bases or defending your own.
