Summary
The Hidden Tesla is a single target defensive building. It is unlocked at Builder Hall level 3.
Before it begins attacking, the Hidden Tesla remains completely invisible to the attacker. Once a unit is within 6 tiles of the Tesla, the Tesla emerges from the ground and begins attacking. Like its Home Village counterpart, it automatically emerges from the ground if it is still hidden when at least 51% of the base is destroyed.
It attacks enemies with electricity, just like its Home Village counterpart. It has the same fire rate and range, however its damage compared to equivalently leveled Hidden Teslas in the Home Village is higher at low levels but lower at high levels.
Offensive Strategy:
Enemies need a 2x2 clear space for a Hidden Tesla, evaluate the worst place for a Tesla placement and deploy accordingly.
Sneaky Archers can show you the location of a hidden Tesla, even when invisible. Placing two sneaky archers of relative level will be able to take down the hidden Tesla.
You can tell the location of an isolated hidden Tesla if an area on the ground is illuminated without having a building on it during an attack. All buildings illuminate the ground, and the hidden Tesla does as well, even when hidden.
Defensive Strategy:
The hidden Tesla can be used to lure your opponent into an air attack, then take out the air units. This is very effective at Builder Hall level three as they only have Beta Minions; when your opponent destroys your Firecrackers and Archer Tower, he/she will send in his/her Beta Minions only to get destroyed by your hidden Tesla.
The hidden Tesla illuminates the ground, so to disguise it, place it near other buildings.
Upgrade Differences
Hidden Teslas undergo significant visual changes at levels 4, 7 and 8.
When initially constructed, the Hidden Tesla consists of a tall, slender wooden lattice structure with a wire coiled up one support. The top of the tower has a metal conducting rod protruding from it. On each side of the tower's base are what appear to be open trapdoors, evidence of the fact that it buries oneself under the ground until an enemy comes through.
The levels 2 and 3, Hidden Teslas gain additional metal conductors hanging down from the top of the tower, and a second wire coiled up the support on the opposite side of the tower.
The level 4 Hidden Tesla acquires its namesake Tesla coil at the top. At level 5, the metal conductor pieces turn golden yellow, and a third coil of wire appears on the front support.
