When you upgrade your Town Hall in Clash of Clans, you’ll notice that the cost of upgrading buildings steadily rises. This trend continues all the way up to the highest Town Hall level, which is Town Hall 15.
At Town Hall 15, you’ll encounter some of the most expensive upgrades within the game. Let’s take a closer look at the most expensive upgrades in Clash of Clans:
- Eagle Artillery to Level 6 (21,500,000 Gold)
- Scattershot to Level 4 (21,300,000 Gold)
- Inferno Tower to Level 9 (21,000,000 Gold)
- Pet House to level 8 (20,500,000 Elixirs)
Eagle Artillery
The most expensive upgrade within Clash of Clans is the upgrade of Eagle Artillery to level 6. This specific upgrade comes with a big price tag of 12,500,000 Gold and becomes available once you’ve reached Town Hall 15.
Upon completing this upgrade, the Eagle Artillery’s damage per hit gets a boost to 525, and its shockwave damage extends to 45. Additionally, its hitpoints rise to 5900 at level 6.
This upgrade also ranks among the longest upgrades in the game, as it requires a full 20 days to reach completion.
Scattershot
Another upgrade that comes with a hefty price tag is taking the Scattershot to level 4. This upgrade is almost as expensive as the Eagle Artillery, requiring 21,300,000 Gold to complete.
The Scattershot is a core defensive building that deals splash damage upon enemy troops. Once upgraded to level 4, it improves the Scattershot’s performance, increasing its damage per second to 200, while its splash damage output rises to 480. Furthermore, the Scattershot’s durability increases to 5100 hitpoints upon reaching this level.
Inferno Tower
The Inferno Tower’s upgrade at Town Hall 15 takes the spot as the third most expensive upgrade in Clash of Clans. This upgrade elevates the Inferno Tower to level 9, demanding a considerable amount of 21,000,000 gold.
Upon reaching this level, the Inferno Tower becomes an even better defense, delivering peak damage of 2,400 in single-target mode and 307.2 in multiple-target mode.
Additionally, its hitpoints soar to 4000, and completing this upgrade takes 19 days.
Pet House
The fourth upgrade that stands out for its expense is the Pet House’s advancement to level 8. Unlike the previous three upgrades, this one calls for Elixirs instead of Gold, specifically 20,500,000 Elixirs.
You can start this upgrade once you reach Town Hall 15. When the Pet House achieves level 8, you unlock the powerful Phoenix as a pet. The Phoenix has a special ability, enabling it to briefly revive a hero when the hero falls in battle.
Moreover, this upgrade strengthens the Pet House, increasing its hitpoints to 1200. Completing this upgrade is a bit time-consuming, as it takes 19 days and 18 hours to finish.
