The Master Builder is a bit of a genius, but honestly, his first big invention is a total headache for most players. We're talking about the battle machine in clash of clans. You unlock this hunk of junk at Builder Hall 5, and it immediately changes how you think about the Builder Base. It’s not just a tank. It’s not just a hero. It is a temperamental, hammer-swinging machine that seems to have a weird obsession with hitting Crusher buildings until it explodes. If you've ever watched your Battle Machine ignore a perfectly good Town Hall—well, Builder Hall—to go smack a high-HP wall while being shot by a Mega Tesla, you know the pain.
But here’s the thing. It’s actually the backbone of any decent 6-star attack strategy in the modern Builder Base 2.0 era.
Ever since Supercell overhauled the Builder Base, the way we use the battle machine in clash of clans has shifted. It used to be this invincible wall of health you’d just spam and forget. Now? It’s a precision tool. If you treat it like a King from the Home Village, you're going to lose. You've got to understand the "Electric Hammer" ability and the specific pathing AI that makes this thing tick. It’s quirky. It’s frustrating. But when it works, it clears half a base by itself.
The Electric Hammer is Basically Your Only Hope
The core of the machine is the ability. Most people just tap it the second it’s off cooldown. That is a massive mistake. The Electric Hammer has three levels of charge. You see those little lightning bolts above the icon? That’s your signal.
Level one gives you a tiny bit of health back and a chain-lightning effect for three hits. Level two is better. Level three? That’s where the magic happens. At level three, the chain lightning hits more targets and deals significantly more damage. It’s tempting to spam it to keep the machine's health up. Don't. You need to time that level three burst for when the machine is deep in the core.
Think about it this way. If you use the ability early, you’re wasting the chain lightning on low-value buildings like Army Camps or Labratories. You want those lightning arcs jumping across the high-damage defenses. The Mega Tesla, the Multi Mortar, and the Air Defense units. Wait for the charge. It’s a game of patience. If the machine dies before level three, you probably dropped it too early or didn't provide enough support.
Understanding the "Suicide" AI
Let’s talk about why your battle machine in clash of clans seems to love dying. It’s the pathing. The Battle Machine follows "Rule of 3" logic, similar to other troops, but because it’s a melee hero with a massive hitbox, it gets distracted easily.
It targets the closest building. Always.
If there is a Crusher tucked behind a wall and a gold mine out in the open, and that gold mine is one tile further away, your machine is going for the wall. Every time. This is why the "funnel" is even more important in Builder Base than it is in the Home Village. You need to use your sneaky archers or your bombers to clear the peripheral junk. If you don't clear the sides, your machine will go on a scenic tour of the exterior of the base while the defenses shred it.
I’ve seen players lose thousands of trophies just because they refused to bring a single Bomber. Bring the Bomber. Open the walls. Guide the machine. It’s a toddler with a sledgehammer; you have to hold its hand.
The Stats and the Grind to Level 30
The journey to level 30 (and beyond) is a long one. Most players grind it out solely to unlock the 6th Builder, also known as B.O.B. It’s a grind. No way around it.
Why the Levels Matter
At level 1, the Battle Machine is basically a glorified barbarian. At level 30, it becomes a genuine threat. The health scaling is the most important part. You need it to survive the initial burst from Double Cannons.
- Survival: At higher levels, the machine can tank multiple hits from a Crusher.
- Regeneration: Each ability activation heals a percentage of health. Higher level = more total health = more HP recovered per hammer swing.
- Damage: The chain lightning damage scales. At max levels, it can one-shot certain minor defenses with the secondary arcs.
Don't ignore your Star Laboratory, but honestly, the battle machine in clash of clans should be your priority for Elixir spending until it’s at least level 25. The power spike you get at level 30 is what makes the transition to higher trophy counts possible.
Battle Machine vs. Battle Copter: The Big Debate
Since the 2.0 update, we have the Battle Copter. A lot of people abandoned the machine the second they got the flying option. Big mistake. Huge.
The Copter is great for sniping and staying out of range of Ground-only defenses like the Cannon or the Crusher. But the Copter is "soft." It has the structural integrity of a wet paper towel. The battle machine in clash of clans is your meat shield.
The best strategy right now? Use the Battle Machine for the first stage of the attack to punch a hole into the core. If it survives, great. If not, you can switch to the Copter for the second stage to clean up the remnants of the second base. Or, keep the Machine for both if the base is ground-heavy. The Machine is a brawler. The Copter is a sniper. Know which one the base requires. If you see a lot of Fire Crackers and Mega Teslas, keep the Machine on the ground.
Advanced Tactics: The "Ability Stall"
Here is a pro tip that most casual players miss. The Electric Hammer animation actually pauses the machine's movement for a split second. You can use this to your advantage.
If your machine is about to walk into the range of a Crusher and you know the Crusher is about to swing, activating the ability can sometimes delay the machine just enough to let a Cannon Cart or a group of minions take out the Crusher first. It’s a micro-timing trick. It takes practice. But mastering the "stall" can be the difference between a 50% one-star and a 100% three-star.
Also, remember that the lightning arcs can hit targets behind walls. If the machine is hitting a wall, and there’s a defense directly behind it, the Level 3 ability will still damage that defense. Sometimes, hitting a wall isn't a total waste of time—if the lightning is doing the heavy lifting.
Synergies That Actually Work
You can't just drop the battle machine in clash of clans and hope for the best. It needs friends.
- Bombers: Non-negotiable. You need to break the first layer of walls so the machine doesn't get stuck in a "kill zone."
- Cannon Carts: My personal favorite. Let the Machine tank the hits while the Carts sit back in "Mortar Mode" and rain fire. This is the "protect the president" strategy.
- Baby Dragons: Use the dragons to pick off the buildings that would distract the Machine’s pathing. Clear the "trash" so the Machine stays focused on the center.
The biggest mistake is dropping the machine after your main army. It’s the tank. It goes in first (or right after the wall breaker). It absorbs the initial traps. If it hits a Spring Trap, well, that's better than your entire stack of Hog Gliders hitting it.
The Mental Game of Builder Base
Let's be real: Builder Base can be tilting. The battle machine in clash of clans is often the source of that tilt. You watch it walk past a 1-HP Builder Hall to hit a Firecracker. It’s infuriating.
But you have to look at the "Next Three Targets." The AI doesn't just see the closest building; it weighs the distance to the three nearest targets. If two of those targets are behind a wall and one is an open Gold Mine 10 tiles away, it might still pick the wall. You have to visualize the "circle" of targets around the machine. If you can’t see a clear path to the core, don't drop it yet.
What Most People Get Wrong About Upgrades
People think they should balance their base. They upgrade a cannon, then a wall, then the machine. Stop.
If you want to progress fast, you rush the battle machine in clash of clans. It is the single most important unit in the Builder Base. A level 30 machine with level 1 defenses will win more matches than a level 5 machine with level 9 defenses. Why? Because the Builder Base is an offensive game. You need to be able to 3-star (or 6-star) your opponent. The machine is the only unit that provides consistent, high-HP value every single match.
Final Actionable Steps for Your Next Raid
Stop treating the Battle Machine like a disposable troop. It’s your win condition.
First, check the base for the Crusher locations. That is your "No-Go" zone. If you can't take out the Crusher with ranged units, you have to path your machine around it or wait until the machine's level 3 ability is ready to burst it down.
Second, look at the Mega Tesla. It deals double damage to the machine. If the Mega Tesla is exposed, use a few sneaky archers to snipe it before the machine gets anywhere near it.
Third, hold your ability. I know, you want to click the shiny button. Don't. Wait for the level three charge. Let the machine take some damage, then pop the level three to heal a massive chunk and chain-react the entire core of the base.
Finally, keep your Elixir focused. If your machine isn't level 30 yet, that should be your only goal. Forget the other troops for a bit. Max the machine, get your 6th builder, and then you can play the game properly.

Go into your next match and focus entirely on the funnel. Don't worry about the 100%. Just focus on making sure that battle machine in clash of clans goes exactly where you want it to go. Once you control the machine, you control the base. It’s that simple, even if the AI makes it feel like rocket science.
Master your funneling by practicing with a single Bomber and the Battle Machine in friendly challenges. Focus exclusively on how the Machine reacts to wall gaps versus building proximity. Once you can predict its movement 90% of the time, start incorporating high-DPS support units like Cannon Carts to clean up behind it.
