Clash of Clans Hidden Tesla Guide: Upgrade Levels, Strategy

The Hidden Tesla tower is the only tower that functions like a trap in Clash of Clans. It occupies just 2×2 tiles and remains hidden until enemies get within 6 tiles of the tower. Despite functioning like a trap, the Hidden Tesla has a health pool like a normal tower and counts as a building for purposes of unlocking the stars resulting from 50% and 100% of a base being destroyed.

The Hidden Tesla is the only tower in-game which has a preferred target: the P.E.K.K.A. Hidden Tesla towers not only deal double damage to the P.E.K.K.A, but they will also specifically target the P.E.K.K.A over other targets if a P.E.K.K.A is in range.

Hidden Tesla Strategy

The Hidden Tesla is the only tower in the game that you get to hide. There are many ways to deploy this tower, as its small size allows it to be placed in tighter places than the average tower.

Strengths and Weaknesses

The Hidden Tesla’s primary strengths are its fast attack speed, its high DPS, its ability to be hidden, and the double-damage this tower deals against the P.E.K.K.A.

The Hidden Tesla’s fast attack speed makes it very effective against light units. Since an appropriately-leveled Hidden Tesla will 1-shot an Archer, it is very effective at destroying Archers given that the tower gets to attack once every .6 seconds. While many other towers will also 1-shot an Archer, none will do so as readily as the Hidden Tesla given the Tesla’s fast attack speed.

The High DPS of the Hidden Tesla (the highest in the game outside of a single-target Inferno Tower) makes it very strong against high-health targets. This is especially the case with enemy P.E.K.K.As, given that the P.E.K.K.A is preferentially targeted by the Hidden Tesla and takes double damage from this tower.

The tower’s ability to be hidden can also be leveraged to the player’s advantage. Note that the tower triggers at a range of 6 tiles, but has a range of 7 tiles. This means that an enemy unit needs to get within 6 tiles of the Hidden Tesla for it to pop, but once the tower pops, it can then hit enemy units from up to 7 tiles away. Hidden Teslas automatically pop when an opponent clears 51% of a base.

All around, the Hidden Tesla is a fairly strong tower and does not have any one particular weakness. It has fairly low HP, and as a result like any single-target tower can get overwhelmed by a large number of enemy units, or by a single very high HP unit (such as a Dragon).

Hidden Tesla Placement

There are many ways to place the Hidden Tesla tower, and there is no right or wrong answer to their placement. Hidden Teslas can often use surprise to their advantage by forcing units that target defenses (like Giants) to go into a funnel where it appears that these units otherwise would not enter (as in there is no other defensive structures located in that funnel).

Lower level players (TH7-early TH9) tend to place their Hidden Teslas on the perimeter of the base. They are less likely to run into high-health units like P.E.K.K.As and high-level heroes coring into the center of their base. Instead, Hidden Teslas on the perimeter are great for picking off Wall Breakers and Archers that players often use to attack the perimeter of the base.

High level players using trophy layouts often place their Hidden Teslas in the center of their base around their Town Hall. Hidden Teslas are strong towers and take up little space, so it is easier to squeeze them in the center of the base than it is to include larger towers here. Hidden Teslas compliment Inferno Towers very well, which are also commonly located centrally in a high-level base.

Hidden Tesla Upgrade Priority

Upgrading the Hidden Tesla should be a very low priority. The reason for this is that Hidden Teslas take a very, very long time to upgrade compared to other towers. They are also not such an essential tower (like the Air Defense or Mortar) where your base will suffer if you upgrade multiple Hidden Teslas at the same time. You can easily have all 4 Hidden Teslas being upgraded simultaneously and still mount an effective defense against enemy attacks.
