Updated for Town Hall 18 (October 2026).
The Giga Inferno at Town Hall 15 is the weapon built into a level 15 Town Hall: a pink-beamed inferno that burns up to four troops at once and leaves a poison cloud when the Town Hall falls. Since October 6, 2025 it has no upgrade levels. Every TH15 Town Hall now fights with the same fixed stats, so there is nothing to research or build for it after your Town Hall upgrade finishes.
How the TH15 Giga Inferno works
The weapon sleeps inside the Town Hall at the start of a battle. It wakes up in one of two ways: something damages the Town Hall (a troop, a hero or a spell), or the attack reaches 51% destruction. A troop walking past does not trigger it.
That sleeping phase changes how some troops path. While the weapon is hidden, the Town Hall is not counted as a defense, so Giants, Balloons, Hog Riders and other defense-only troops walk right past it. Once the inferno pops up, the Town Hall becomes a valid target for them.
When active, it locks onto as many as four ground or air targets inside its 10-tile range and fires a beam at each one. The beams tick fast (every 0.128 seconds) for small hits, so very little damage is wasted on troops that are already dying. Each beam does the same damage per second, which means a single troop only ever takes one beam’s worth. Three spare beams sit idle if there is just one target in range.
The poison death bomb
Destroying the TH15 Town Hall sets off a blast that covers 4.5 tiles around it. The blast hits for 1,000 damage and then leaves a poison cloud for 12 seconds. Inside the cloud, troops take poison damage (up to 180 per second), move 50% slower and attack 50% slower. That combination is what wipes out Witches, Bowlers, Wizards and Balloons that crowd the Town Hall at the end of an attack.
TH15 Giga Inferno stats (current)
| Stat | Value |
|---|---|
| Damage per second, per target | 300 |
| Damage per hit | 38.4 |
| Attack speed | 0.128s |
| Targets at once | 4 (ground and air) |
| Range | 10 tiles |
| Death damage | 1,000 |
| Death blast radius | 4.5 tiles |
| Poison damage per second (max) | 180 |
| Poison slow (movement and attack) | 50% / 50% |
| Poison duration | 12 seconds |
| Town Hall 15 hitpoints | 9,600 |
Compared with the TH14 Giga Inferno, this version hits 20 harder per second, adds 100 death damage, widens the blast from 4 to 4.5 tiles and sits on a tougher Town Hall (9,600 hitpoints instead of 8,900). Range, targets, poison strength and poison length are unchanged.
Placing a TH15 Town Hall on defense
Treat the Town Hall as a real defense at TH15. It covers a 10-tile circle, so a central spot lets it reach most of the core. Two things are worth planning around:
- An attacker can wake the weapon early with a single Earthquake Spell so that Balloons or Hog Riders turn toward the Town Hall. A single-target Inferno Tower or the Monolith nearby punishes those big targets.
- The weapon is weak against a lone tank because only one beam can hit it. Splash defenses and the two Spell Towers you unlock at TH15 help cover that gap.
Leaving the Town Hall in a big empty compartment can tempt attackers into sending a siege machine straight at it, so pick that layout on purpose, not by accident.
How to attack the TH15 Giga Inferno
- Freeze it. A Freeze Spell stops the beams while your troops work on it or walk past it.
- Take it down early with something small. A Battle Blimp or Wall Wrecker carrying Clan Castle troops, or a hero, can kill the Town Hall before your main army arrives. Then the poison cloud only lands on a few units.
- Keep swarms outside 4.5 tiles when it dies. The blast radius is smaller than the weapon’s 10-tile range, so long-range units such as the Archer Queen can shoot it from a safe distance.
- Use troops that dodge the bomb. Miners underground when the Town Hall falls avoid the blast, as long as they don’t surface into the cloud.
- Plan for the poison, not only the blast. The Grand Warden’s Eternal Tome can block the hit itself, but the 12-second cloud keeps slowing and damaging troops after the Tome runs out. A Healing Spell or the Healing Tome on top of the cloud keeps them alive.
A Queen Charge with Healers can usually grind the Town Hall down if no other defense covers it, because only one beam reaches the Queen. Bring a Rage Spell if the Healers fall behind.
What changed: weapon levels removed (October 2025)
From the TH15 release on October 10, 2022 until October 2025, this Giga Inferno had five levels of its own, and each one cost Gold and builder time after the Town Hall upgrade. Supercell announced on August 22, 2025 that weapon levels would go away for TH12 through TH15 because they slowed down midgame progress. The Ranked update on October 6, 2025 made it official.
- Every TH15 weapon now has the stats of the old maxed version, with one exception: death damage dropped from 1,100 to 1,000 in the same update.
- Upgrades running at the time were cancelled, and the Gold was not refunded.
- The Roman numerals on the Town Hall that used to show the weapon level no longer separate one TH15 from another. Every TH15 Town Hall fights the same.
Earlier balance changes still apply: damage was cut on September 28, 2023 and again for the higher levels with TH16 on December 12, 2023, when the poison duration also dropped from 16 seconds to 12.
Other Town Hall weapons
The Giga Tesla (TH12) and the TH13 Giga Inferno came first. TH16 keeps a Giga Inferno with a stronger death bomb (1,100 damage) and 10,000 Town Hall hitpoints. At TH17 the Town Hall merges with the Eagle Artillery into the Inferno Artillery, and TH18 replaces the weapon with Guardians. The Town Hall guide covers each step.
FAQ
Can you still upgrade the Giga Inferno at TH15?
No. Since October 6, 2025 the TH15 Giga Inferno has a single set of stats and no upgrade button.
How much damage does the TH15 Giga Inferno do?
300 damage per second to each of up to four targets, plus 1,000 damage in a 4.5-tile blast when the Town Hall is destroyed and up to 180 poison damage per second for 12 seconds after that.
What triggers the Giga Inferno?
Any damage to the Town Hall, or the attack reaching 51% destruction. Troops simply walking into range do not wake it.
