The first Clash of Clans Town Hall 14 feature has been revealed: Defensive Builder's Huts with weaponized turret and an active Builder to repair defenses. The popular mobile strategy game Clash of Clans has an ingenious Auto Upgrade option aimed to help players who have been inactive for an extended period of time. This feature, which is triggered after 90 days of inactivity, and can only be triggered once per year intends to help returning players by automating the upgrading process, allowing That's a 6.3 gem-per-hour ratio (736 gems / 116 hours). The lvl 8 Archer Tower (3 day upgrade) has 14.5 hours left, and costs 160 gems to finish. That's an 11 gem-per-hour ratio (160 gems / 14.5 hours) With this (albeit) very limited data, it seems that the longer the upgrade time, the lower (and more efficient) gems-per-hour cost you receive. These times assume 6 builders, no Gold Pass boosts and no magic item usage. If you purchase the Gold Pass and have magic items to use, it will be considerably quicker/cheaper.

The Hidden Tesla is a defensive building with a twist: similar to a Spring Trap or Bomb, it stays hidden and appears when a ground or air unit gets close, or when 51% of the base is destroyed. However, unlike a trap, it does not have to be rearmed after being deployed. The Hidden Tesla is unlocked at Town Hall level 7. Players will need to spend Gems to get the Goblin Builder in Clash of Clans. The Gem cost depends on the construction or upgrade time of the task. The longer the upgrade time, the higher the Gem cost. However, boosts from the Season Pass can reduce the Gem cost. The Goblin Builder can only be unlocked if the player is Town Hall level 7 or above “The Clock Tower makes things happen faster in your village! Collect resources, research and build faster.” The Clock Tower is a building that can be repaired at Builder Hall Level 4.
