Reinforcement Camp

"Reinforcement Camps provide helpful reinforcements during battles when reaching the corresponding stage."


  • The Reinforcement Camp houses Builder Base Troops which you can use for Builder Battles, similar to Army Camps. Unlike troops in Army Camps, troops in Reinforcement Camps are not immediately usable; they can only be used if the first stage of a Builder Base is completely cleared.
  • Reinforcement Camps take up a 3x3 space.
  • Each Reinforcement Camp houses one particular type of troop, rather than collectively housing a combination of troops. The number of troops that each Reinforcement Camp can house will depend on the level of that troop, if possible.
  • Each Camp trains instantaneously and does not cost any Builder Elixir.
  • You must have all your Army and Reinforcement Camps full before you can start a Builder Battle.
    • All the troops in the camps that are trained will be used up even if you do not deploy them, though it doesn't have any impact due to instant training.
  • The build cost and build time for the Reinforcement Camp increases the more you own. At Builder Hall level 10, you can have a maximum of two Reinforcement Camps. Combined with the Army Camps, this allows for a maximum of eight camps' worth of troops in a single attack.
  • Just like the Builder Base Army Camps, they cannot be upgraded. However, some troops allow more of their kind to fit in a single Army Camp if they are sufficiently upgraded in the Star Laboratory.
