If you’re sitting at Town Hall 11 or higher, you know the struggle: your Archer Queen is down for a week, every one of your five builders is tied up on long upgrades, and you’re staring at that empty 6th builder slot wishing for an extra set of hands.
I’ll be real with you — even though B.O.B (the 6th builder) has been in Clash of Clans for years, I only unlocked him recently. His hut was actually sitting in my base for ages and I had no idea I could activate it. I wasted a lot of time doing things the hard way, but you don’t have to. This guide walks you through exactly how to get 6th builder in CoC faster and with fewer headaches.
Can You Unlock the 6th Builder Without Builder Hall 9?
No. You must reach Builder Hall 9 to unlock B.O.B’s Hut and start the quest. Even if you meet all task requirements at Builder Hall 8 or lower, the game won’t let you proceed until BH9 is complete. If you’re serious about unlocking the 6th builder, prioritize getting to BH9 (or BH10) as soon as possible.
🧾 What You Actually Need to Unlock B.O.B
Before B.O.B can join your village, you must complete these four tasks after placing his Hut at BH9:
- Gear up 3 defenses in your Home Village.
- Get a Builder Base troop to Level 18.
- Get a Builder Base defense to Level 9.
- Reach a combined Hero Level of 45 (Battle Machine + Battle Copter).
Step 1: Complete the Home Village Gear-Ups
The first challenge is in your Home Village. When you gear up a defense, your Master Builder must leave the Builder Base and travel to the Home Village — pausing your Builder Base progress.
You must gear up three defenses:
- Cannon: Fast and easy.
- Archer Tower: Requires at least Level 10.
- Mortar: The longest timer by far.
💡 Pro tip: Use a Book of Building on the Mortar if you have one. It’s the longest task here and skipping it puts your Master Builder back to work faster.
Step 2: Reach a Level 18 Builder Base Troop
The fastest way to finish this task is to upgrade whichever troop is already closest to Level 18. Don’t chase the meta — go for what needs the least time.
When I was doing this, I used Night Witches with a tanking strategy (Giants up front, bats behind). It made daily loot grinding easier while I focused on upgrades.
Step 3: Upgrade One Defense to Level 9
You only need one defense at Level 9 in the Builder Base. The easiest path is usually:
- Multi Mortar → often already near Level 8 from other tasks
- Or finish a Firecracker, Crusher, or Tesla if it’s already high
The key here is efficiency — don’t start from scratch if you can finish something that’s already halfway there.
Step 4: Reach a Total Hero Level of 45
This means your Battle Machine + Battle Copter combined must reach Level 45.
Thanks to Builder Base 2.0:
- You unlock the Battle Copter at BH8 (it starts at Level 15)
- If your Battle Machine is Level 20, you’re already halfway there
A good playstyle is to alternate upgrades so you always have one hero ready to use while the other levels up.
For most players searching how to get 6th builder in CoC fast, hero upgrades are the longest and most resource-heavy part of the grind, so planning these levels properly makes a huge difference.
Speeding Up the Progress
Want this done faster?
- Use Raid Medals at the Trader every week to buy Builder Elixir/Gold
→ This can save months of waiting. - Keep your Clock Tower active daily
→ Those boosts add up significantly over time.
🎉 Unlocking B.O.B
Once all four tasks are finished:
- B.O.B’s Hut automatically upgrades to Level 5
- The 6th builder joins your Home Village permanently
- The original Master Builder stays in your Builder Base
→ You now have two productive builder pools
This extra builder is a game changer, especially from TH11 onward where core upgrades routinely take 7–14 days.
Now that you understand how to get the 6th builder in CoC, the next step is protecting your loot and heroes while you complete the upgrades.
❓FAQ
How long does it take to get the 6th builder in CoC?
For most players, it takes about 2–4 months, depending on hero levels and how consistently you collect loot and use Raid Medals.
Is the 6th builder worth it?
Absolutely. A 6th builder permanently speeds up Home Village progression — huge advantage in late TH11 and beyond.
Can I move the 6th builder back to the Builder Base?
Yes. You can swap the Master Builder and B.O.B between villages, but most players keep B.O.B in the Home Village for long upgrades.
