Your village is always safe from Clan War attacks because these battles are fought in a different area than the regular game. 

Even when the War Base is an almost identical copy of your village, it is important to remember that this War Base used during Clan Wars is a separate entity from your village.

Using our new Village Editor and layout keeper, you may have up to 3 regular Village layouts, and 3 War Bases simultaneously. That's 6 layouts in total.

From their War Base, players prepare and attack War Bases instead of from their regular village. Your village’s resources, Trophies and Shield are never at risk during a Clan War.
