Hey Chief! Overhauled with the May 2023 Builder Base 2.0 update, the Builder Base is CoC's second village running on its own Builder Gold and Builder Elixir economy, with exclusive troops, defenses, and Hero Machines. Unlocked at Town Hall 4, it adopts a multi-phase combat format from BH6 onward, capped at six stars per attack. Most importantly, it's the only route to unlocking B.O.B - the sixth builder who accelerates your Home Village's late-game progression.
For players who want to skip the early grind, particularly for unlocking additional Builders, LootBar is a trusted and affordable platform for topping up Gems, saving considerable time at the most critical stage of the account.

A brief introduction to the Builder Base
Clash of Clans Builder Base
Often called "Night Mode" for its dark visual style, the Builder Base is a self-contained second village reached by repairing the boat on your Home Village shore at Town Hall 4. Everything resets on this side, except gems, meaning you grind a fresh economy, army, and base from scratch. After the 2.0 rework, the mode leans into tight, tactical play, swapping massive armies for a small lineup of specialized troops across two-stage battles that reward smart composition and timing over spam.
The new Hero Machines
Master Builder doesn't fight on foot; he rides into combat in one of two Hero Machines. Both use a three-level charge system: tap the ability early for a weaker burst, or wait roughly 40 seconds for a fully charged level 3 effect with bigger damage and more healing.
| Heroes | Description |
Battle Machine | Melee exo-suit wielding the Electric Hammer. Activating the ability stuns briefly, restores HP, boosts damage for the next three attacks, and at high levels adds chain lightning that arcs to nearby targets. |
Battle Copter | Flying ranged hero that snipes buildings from a distance. Its Bomb Rush ability sends it diving onto a target to drop a heavy AoE bomb while regenerating health. |
You can only deploy one Hero Machine per stage, but at the end of Stage 1, you can keep the same one or swap to the other at full HP.
The new troops and their abilities
Clash of Clans Builder Base New Troops
Builder Base 2.0 added active and passive abilities to almost every unit, which is what makes the troop roster feel completely different from the Home Village. Here's the full list:
| Troops | Ability |
Raged Barbarian | Melee swarm unit with the Rage passive, gaining boosted speed and damage for the first 22 seconds. |
Sneaky Archer | Ranged ground sniper with Cloak, staying invisible to defenses for the first 11 seconds. |
Boxer Giant | Tank that targets defenses. His Power Punch passive deals extra damage on the first hit, and the tappable Boxer Block briefly makes him invulnerable. |
Beta Minion | Ranged flyer with Power Shot, firing faster and farther with bonus damage on his opening attacks. |
Bomber | Wall-breaker that throws explosives. His Bouncing Bomb cooldown ability lets a single shot bounce twice for massive wall damage. |
Baby Dragon | Aerial splash attacker with the Tantrum passive, dealing extra damage when no other air units are nearby. |
Cannon Cart | Mobile siege unit with a Change Mode toggle, swapping between a fast cart form and a stationary long-range mortar. |
Night Witch | Ranged ground caster that continuously spawns Bats. Her Bat Swarm, one-time active, releases a massive wave of Bats to overwhelm defenses. |
Drop Ship | Flying support unit that periodically drops Skeletons. Its Skeleton Bomb active deals AoE damage and spawns ground Skeletons that continue attacking. |
Power P.E.K.K.A | Heavy melee bruiser with Overcharge, a tappable explosive AoE that detonates around her. |
Hog Glider | Aerial-to-ground unit that flies over walls and dismounts into a Hog Rider when destroyed. His Stunning Glide ability stuns defenses on impact. |
Electrofire Wizard | Glass cannon unlocked at BH10 with a Change Mode toggle. Inferno Mode locks a beam onto a single target with ramping damage; Electro Mode fires chain lightning that hits up to four nearby buildings. |
The new defenses and other buildings
Clash of Clans Builder Base New Defenses
New Defenses and Traps
Builder Base defenses lean way harder into mechanical creativity than the Home Village. The full defensive lineup:
| Buildings and Defenses | What They Do |
Canon | Basic single-target ground defense, dependable for soaking early-game pressure. |
Double Canon | Fires two rapid shots per cycle, excellent against tanks like Boxer Giants and Battle Machines. |
Archer Tower | Long-range single-target tower that hits both ground and air. It can switch between Long Range and Short range for faster attack Speed |
Hidden Tesla | Cloaked anti-ground tower that activates when troops get close, perfect surprise damage. |
Fire Craker | Long-range anti-air burst defense that lobs explosive shots at incoming flyers. |
Crusher | Stomps down on ground units in a wide radius for massive splash damage. |
Guard Post | Spawns a defending troop that wanders the base and engages attackers. |
Air Bombs | Hidden traps that fire upward at aerial troops. |
Multi Mortar | Saturation defense fires volleys of shells across a wide area. |
Roaster | An anti-air and anti-ground continuous-damage tower that locks onto multiple targets. |
Giant Cannon | Long-range piercing shot that rips through tanky pushes. |
Mega Tesla | Hidden DPS spike with massive damage, ideal for catching swarms off guard. |
X-Box | Anti-air or anti-ground toggle, the same monster you know from the Home Village. |
Walls | Standard barrier that funnels troop paths and breaks up clusters. |
Mines and Mega Mines | Pressure-triggered ground explosives, with Mega Mines hitting much harder. |
Push TTraps and Spring Traps | Redirect or eject troops away from your core defenses. |
Non-defensive buildings matter just as much:
| Buildings | Description |
Builder Hall | The heart of Stage 1, destroying it earns attackers a star and unlocks new content as you upgrade. |
O.T.T.O's Outpost | The Stage 2 equivalent of the Builder Hall, introduced at BH6 when the multi-stage system activates. |
Builder Barracks | Trains and unlocks new Builder Base troops as you upgrade it. |
Army Camp and Reinforcement Camp | Hold your initial army and your Stage 2 reinforcement slots. |
Star Laboratory Research | s and levels up your troops. |
Clock Tower | Boosts upgrade and resource production speed during its window. |
Healing Hut | Restores HP to surviving troops between Stage 1 and Stage 2. |
Gem Mine | Slowly produces free gems over time. |
Gold Mine and Elixir Collector | Passive Builder Gold and Builder Elixir income. |
Gold Storage and Elixir Storage | Hold your accumulated resources. |
Battle Machine Altar and Battle Copter Altar | Where your Hero Machines rest and upgrade. |
B.O.B's Control | The building at BH9+ that tracks your progress toward unlocking B.O.B. |
What the Builder Base does for your Home Village: unlocking B.O.B
The single biggest reason competitive players actually push their Builder Base is B.O.B, formerly known as O.T.T.O. He's a robotic sidekick the Master Builder constructs and sends over to the Home Village, where he acts as a permanent sixth builder. That sixth builder shaves weeks off late Town Hall progression, especially at TH15 and above, where upgrades regularly run 7 days or longer.
Unlocking B.O.B requires hitting Builder Hall 9 first, then working through a checklist of upgrade requirements, which usually involves bringing a Double Cannon, Archer Tower, Multi Mortar, and Baby Dragon up to set levels, along with raising your Battle Machine and Battle Copter to a combined level benchmark. The path is a slow burn, but as Clash Ninja's B.O.B guide points out as well, no other reward in the Builder Base comes close to matching it.
Pro tips for the Builder Base
A few habits separate average Builder Base play from genuinely high-level output:
- Hold your Hero Machine ability for the level 3 charge. Tapping at level 1 wastes most of the value. Wait the full 40 seconds unless you desperately need the heal to keep your machine alive.
- Protect your Stage 1 troops. Surviving units carry over to Stage 2 with partial healing from the Healing Hut, so treat Stage 1 as setup for the bigger six-star push instead of throwing everything at the wall.
- Scout the layout before deploying. Walk your eyes across the base first. Bombers and Cannon Carts can pre-clear traps and walls if you read the path correctly, saving your heavy hitters for the core.
- Break up clusters in your base design. Spacing out buildings prevents Baby Dragons and Bombers from multi-hitting, and overlapping defense ranges keep your key buildings supported.
- Use Push Traps and Spring Traps to redirect heavies. Boxer Giants and Power P.E.K.K.A. are predictable; push them away from your core or off the map entirely.
- Don't skip the Clock Tower boost. It accelerates everything during its window, making it one of the best resource and upgrade tools in the Builder Base.
Conclusion
The Builder Base has gone from a forgotten side village to one of the most rewarding parts of Clash of Clans, especially with the multi-stage attack system, Hero Machine charge mechanics, deep troop roster, and the long game payoff of B.O.B. Master the troop abilities, build defenses that punish lazy compositions, and treat every attack like a small puzzle instead of a spam fest. Push your way to BH10, lock in that sixth builder, and watch your Home Village progression accelerate in a way you can't get from any other system in the game. If you want to accelerate the grind to BH10 and B.O.B, grabbing gems through a LootBar, Clash of Clans Top Up at competitive rates is the fastest way to skip the slow stretches.
