Traps/Builder Base




 * Summary
 * Traps are relatively inexpensive structures that remain hidden until they are activated by an attacking troop moving into their trigger radius. They can greatly improve the effectiveness of a village's defense if properly placed.
 * Unlike the Traps in the Home Village, these Traps do not need to be re-armed; they will always be ready for the next battle.
 * Although commonly thought of as a trap, the Hidden Tesla is not listed here as it actually a hidden Defensive Building and does not need to be re-armed for re-use.
 * Even though traps are classified as "Defensive Buildings/Builder Base", they are not buildings and do not need to be triggered/destroyed for your enemy to reach 100% destruction (nor do they count toward it).
 * Traps do not need the Master Builder to be available in order to be placed, however the Master Builder needs to be available to upgrade them.


 * Upgrade facts
 * Currently all permanent traps have upgrade levels.
 * Upgrading is available as soon as the trap is bought from the shop.
 * Traps are upgraded using the Master Builder.
 * Upgrade times are relatively short compared to building upgrades, taking at most 8 hours to build.
 * Most levels of traps have a relatively low cost compared to buildings.
 * Different trap types have different upgrades and functionalities: some deal damage whilst others move troops to another part of the base.
 * Traps being upgraded are visible to enemies; it is usually a good idea to relocate them while they are being upgraded to ensure that enemies don't know where traps aren't. However, remember to replace them when it is finished upgrading.
 * Each trap must be upgraded individually. Upgrading one trap does not upgrade all traps of that type.
 * Attackers can deploy troops on top of traps even when they are being upgraded.


 * Using traps
 * Traps in the Builder Base do not require re-arming, unlike those in the Home Village. They will remain armed for the next battle.
 * Once a particular trap is upgraded, it is permanently upgraded. Upgrade levels don't disappear when it is triggered.
