Town Hall 12: Upgrade Order, Priorities and Common Mistakes
Town Halls
Updated: 18 September 2026 · By the Goblins Farm team
Town Hall 12 introduces siege machines, which change how Clan Castle troops reach the core.
What changes at this level
The Workshop unlocks siege machines, which carry your donated Clan Castle troops into the middle of a base rather than making them walk. This is a substantial change to how war attacks are built.
Upgrade order
The framework does not change between Town Halls, only the specifics. Keep the laboratory running, keep a hero upgrading where you have one, and keep every builder busy. Within that:
- Heroes, continuously, still the main constraint.
- Workshop and siege machine research.
- Laboratory research on your war army.
- Defence levels, prioritising the categories your replays show failing.
- Walls with surplus.
The general reasoning behind this ordering is set out in upgrade priority.
Mistakes that cost you weeks here
Not requesting a siege machine. They are donatable, they cost your clanmates little, and attacking without one at this level is voluntarily giving up the value of your Clan Castle troops.
Reading the tables below
The loot table shows what an attacker can take from a Town Hall 12 village: the share of your storages that is available and the cap per attack. That is the number that decides whether you are worth attacking, and it is why spending down before you log off works. The building table shows what you can own at this level and what is new.
How available loot is calculated in general is covered in loot mechanics.

Frequently asked
What should I upgrade first at Town Hall 12?
Army camps and laboratory research before anything else, since they improve every attack you make at this level, then storages so you can afford later upgrades, then whichever defence category is weakest. Walls last, using surplus.
How long does Town Hall 12 take to complete?
It depends entirely on how consistently you keep builders, the laboratory and a hero running rather than on how much you play. Players who never leave a builder idle finish a Town Hall in a fraction of the time of players who log in twice a week, regardless of skill.
