Updated for Town Hall 18 (October 2026).
The Giga Tesla is the weapon inside a level 12 Town Hall. It zaps up to four ground or air troops at once for 140 damage per second each and explodes for 500 damage when the Town Hall is destroyed. It used to have five upgrade levels, with the death explosion tied to level 5. Since October 6, 2025 those levels are gone, and every TH12 Town Hall gets the full weapon, explosion included, as soon as the upgrade finishes.
How the Giga Tesla works
Think of it as an oversized Hidden Tesla living in the roof of the Town Hall. A trap door opens and the Tesla rises when one of two things happens:
- the Town Hall takes damage from a troop, hero or spell, or
- the attack reaches 51% destruction.
Troops walking into range do not trigger it. Until it rises, the Town Hall is treated as an ordinary building, so defense-only troops such as Giants, Balloons and Hog Riders walk past it. Once the Tesla is up, they will target the Town Hall like any other defense.
Active, it hits up to four targets within 10 tiles every half second for 70 damage per zap. Each target gets its own stream of zaps, so a single troop standing alone only takes 140 damage per second no matter how many targets the weapon could handle.
Giga Tesla stats (current)
| Stat | Value |
|---|---|
| Damage per second, per target | 140 |
| Damage per hit | 70 |
| Attack speed | 0.5s |
| Targets at once | 4 (ground and air) |
| Range | 10 tiles |
| Damage when destroyed | 500 |
| Death explosion radius | 4 tiles |
| Town Hall 12 hitpoints | 7,500 |
There is only one row of stats now. Any table showing Giga Tesla levels 1 to 5 with upgrade costs is out of date.
The level 5 explosion question
Many players still search for the “level 5 Giga Tesla explosion” because older guides said the death bomb only showed up once you maxed the weapon. That was how it worked before October 2025: the change history only lists death damage for level 5. Two changes since then matter:
- On June 3, 2024 the explosion was cut from 1,000 damage to 500.
- On October 6, 2025 weapon levels were removed and every Giga Tesla got the old maxed stats, so every TH12 Town Hall now explodes for 500 damage in a 4-tile radius.
The blast is plain damage. It does not slow or poison troops; those effects start with the TH13 Giga Inferno and the TH14 Giga Inferno.
Defending with a TH12 Town Hall
TH12 adds another Hidden Tesla and a third Inferno Tower, and the Workshop for siege machines. Since the Giga Tesla is weak against a single tank, keep a single-target Inferno Tower within reach of the Town Hall. That also covers the case where an attacker wakes the Tesla early so their Balloons or Hog Riders turn onto it.
Attacking the Giga Tesla
- A Freeze Spell stops it from firing while your troops push past.
- One Earthquake Spell on the Town Hall wakes it up on your schedule, which lets nearby Balloons target it right away.
- A Healing Spell keeps troops alive under its zaps. At 140 per second per target, the Giga Tesla has the lowest damage of any Town Hall weapon, so healing keeps up with it more easily than with a Giga Inferno.
- Miners are a strong pick against it. Underground when the Town Hall pops, they skip the explosion.
- The explosion covers 4 tiles and the Tesla reaches 10, so the Archer Queen can finish the Town Hall from outside the blast.
If the Town Hall sits alone in empty space, a Battle Blimp or Wall Wrecker loaded with Clan Castle troops can take it out on its own. The explosion then only hits those Clan Castle troops, and your Grand Warden’s Eternal Tome stays free for later in the attack.
What changed over time
| Date | Change |
|---|---|
| June 11, 2018 | Giga Tesla added with the TH12 update, 5 levels. |
| September 28, 2023 | Damage cut by 20% at every level. |
| June 3, 2024 | Damage cut by 20 more per level; level 5 death damage halved from 1,000 to 500. |
| October 6, 2025 | Weapon levels removed for TH12 to TH15. The weapon arrives maxed; upgrades in progress were cancelled with no refund. |
Supercell first announced the removal on August 22, 2025, saying weapon levels were slowing down midgame progression and weren’t as meaningful as other upgrades.
FAQ
Can I still upgrade the Giga Tesla?
No. It has no levels since October 6, 2025. Upgrading your Town Hall to 12 gives you the finished weapon.
How much damage does the Giga Tesla explosion do?
500 damage within 4 tiles of the Town Hall, with no slow or poison.
What replaces the Giga Tesla at TH13?
The Giga Inferno, which uses fast inferno beams and a death blast that slows troops.
