TH12 Upgrade Guide 2026: What to Upgrade First

This TH12 Upgrade Guide shows exactly what to upgrade first, what to ignore, and how to grow faster without wasting resources or time on bad decisions.

🚀 Quick Start (Don’t Think, Just Do This)

We just hit Town Hall 12. New buildings and level. New grind. Same pain.

Here’s what we do immediately:

  • Drop all new buildings (Inferno, Workshop, traps… everything)

  • Start Laboratory upgrade first (always)

  • Put one troop upgrade running BEFORE upgrading lab (don’t waste time)

  • Keep all builders busy, because idle builder = wasted life

Big mistake?
Upgrading random defenses because they “look cool”.
We’ve done it. Regretted it. Moved on.

🧠 The Simplest Upgrade Strategy

Here’s the thing.

At TH12, offense = everything.

If you can farm → you can upgrade faster → you win long term.

So yeah… we say:

  • Offense first

  • Heroes always running

  • Defense later

But then we break our own rule during CWL.
Because fighting with sleeping heroes feels illegal.

🏗️ Building Priority (Step-by-Step Order)

No guessing. Just follow this.

Building Priority - TH12 Upgrade Guide

Step 1: Core Stuff First

  • Laboratory

  • Workshop (Siege Machines = huge boost)

  • Clan Castle

Step 2: Army Boost

  • Army Camps (big jump in housing space)

  • Barracks / Dark Barracks

Step 3: Hero Stuff

  • Hero upgrades running constantly

  • Blacksmith (for abilities — more on that later)

Step 4: Unlock Power

  • Yeti

  • Headhunter

  • New spells

Step 5: Defenses (in order)

  • Eagle → Infernos → X-Bows → Air Def

  • Then everything else

Step 6: Ignore Till Late

  • Storages

  • Collectors

Yeah… feels wrong. Still works.

🧪 Laboratory Priority (What Actually Matters)

We don’t upgrade everything. That’s how people get stuck for months.

We pick a lane.

Easy farming path (no brain needed):

  1. Dragons

  2. Balloons

  3. Lightning Spell

  4. Rage Spell

  5. Baby Dragon

That’s it.

You now have a spam army that works.

👑 Hero Upgrade Plan (The Pain Section)

We won’t sugarcoat this.

Heroes are everything at TH12.
Also… they’re always upgrading. Always.

What we do:

  • Keep at least 1–2 heroes down at all times

  • Focus:

    • Queen first (always)

    • Warden next

    • King… whenever we remember 💀

During CWL?

We stop hero upgrades.

Yes, we just contradicted ourselves.

But fighting wars with no heroes feels like attacking with Goblins only. Not fun.

⚙️ Blacksmith / Equipment (Skip or Smart Invest?)

This is where people waste resources.

We don’t.

Only upgrade:

  • Abilities we actually use

  • Stuff close to max

Ignore:

  • Random abilities “just in case”

Because ore is rare. Painfully rare.

Think of it like upgrading skins in a game you don’t even play. Why?

⚔️ Army You Should Use (Keep It Brain-Dead Simple)

We like simple. Simple wins.

Farming Army:

  • Mass Dragons 

  • Mass Sneaky Goblins

Drop. Rage. Win. Move on.

Want to triple more consistently?

Then yeah… you’ll need actual strategy.

That’s where Best TH12 attack strategies come in.
Because spam works… until it doesn’t.

🛡️ Defense Upgrade Order 

Not all defenses are equal. Some are just… decorations.

Defense Upgrade Order: TH12 Upgrade Guide

Upgrade first:

  • Eagle Artillery

  • Inferno Towers

  • X-Bows

  • Air Defenses

Mid:

  • Wizard Towers

  • Teslas

Last (sorry…):

  • Cannons

  • Mortars

Mortars feel like background noise at this point.

💰 Resource & Builder Management

This is where we quietly win.

Rules we follow:

  • Never let builders sit idle

  • Dump extra gold into walls

  • Keep lab running 24/7

Also…
If you’re overflowing loot, your base is the problem.

Fix that with better layouts from Free Best TH12 Bases.
Otherwise, you’re just farming for others.

🧱 Builder Base (Don't You Want the 6th Builder?)

We ignored it too.

Big mistake.

Why it matters:

  • 6th builder = HUGE progress boost

What we focus on:

  • Upgrading Heros

  • Required lab and building upgrades only

It’s grindy. No way around it.

But worth it.

🎯 Mistakes Most Players Make

We’ve done all of these. So yeah.

  • Upgrading defenses too early

  • Ignoring heroes

  • Random lab upgrades

  • Wasting ore on useless abilities

  • Letting builders sit idle (this one hurts)

🏆 Easiest Way To Upgrade 2x Faster

We all think progress = better attacks and more farming. Not really.

At TH12, if your base is weak, you don’t just lose… you get wiped and drop trophies fast.

Here’s the loop:

  • Weak defense → more 3-stars

  • Lower trophies → worse rewards

  • Less loot → slower upgrades

Now flip it:

  • Strong base → fewer losses

  • Higher leagues → better loot + ores

  • Faster upgrades without burning out

So yeah… defense quietly speeds everything up.

If you want that edge, our TH 12 base pack is built to help you defend better, stay higher, and progress faster.

Because at this stage, it’s not just about farming more… it’s about keeping what you farm.

🔄 When to Upgrade to TH13?

At some point, you’ll feel “done”.

You’re not.

But you’re ready enough.

We don’t max everything perfectly.
We move when:

  • Core offense is strong

  • Heroes are decent

  • Farming is easy

That’s it.

If you made it this far, you’re already ahead of most players.

Now go upgrade something.
Or don’t. We’ll probably change our mind tomorrow anyway.

Questions

Start with Laboratory, Army Camps, and Clan Castle. These boost your attack strength immediately and help you farm faster.

Focus on offense first. Strong attacks help you earn more loot, which speeds up all other upgrades.

Upgrade Archer Queen first, then Grand Warden, then Barbarian King. Queen gives the most value in attacks.
