Updated for Town Hall 18 (October 2026).
The Builder Barracks is the building that trains your Builder Base army. You get one, repaired when your Builder Hall reaches level 2, and each of its 12 levels unlocks one more troop, ending with the Electrofire Wizard at Builder Hall 10. Training is free and instant, and since Builder Base 2.0 every troop it unlocks arrives at a set starting level and has its own ability.
How the Builder Barracks works
The Builder Barracks does not produce troops over time the way the Home Village Barracks once did. You pick a troop for each Army Camp and Reinforcement Camp, and it is ready at once, at no cost. Training time was removed back in March 2020.
- You can change your troops right up to the start of a battle, and swap unused or reinforcement slots again before Stage 2.
- Upgrading the Builder Barracks does not stop it. You can still train and attack while it is under construction.
- It is a 3×3 building that has to sit on Stage 1. Its hitpoints grow from 300 at level 1 to 1,450 at level 12.
- Troop levels come from the Star Laboratory, not from the Barracks. The Barracks only decides which troops you have.
Builder Barracks levels and the troops they unlock
Builder Base 2.0 (May 15, 2023) made newly unlocked troops skip their early levels. The starting level column shows where each troop begins, so a Hog Glider unlocked at Builder Hall 9 is already level 15. Costs are in Builder Elixir.
| Level | Troop unlocked | Troop starts at level | Builder Hall needed | Hitpoints | Cost | Build time |
|---|---|---|---|---|---|---|
| 1 | Raged Barbarian | 1 | 2 | 300 | 1,000 (paid when Builder Hall 2 repairs it) | – |
| 2 | Sneaky Archer | 1 | 2 | 350 | 4,000 | 1m |
| 3 | Boxer Giant | 3 | 3 | 400 | 10,000 | 10m |
| 4 | Beta Minion | 3 | 3 | 460 | 25,000 | 30m |
| 5 | Bomber | 5 | 4 | 550 | 100,000 | 3h |
| 6 | Baby Dragon | 5 | 4 | 650 | 150,000 | 6h |
| 7 | Cannon Cart | 7 | 5 | 750 | 300,000 | 9h |
| 8 | Night Witch | 9 | 6 | 850 | 500,000 | 1d |
| 9 | Drop Ship | 11 | 7 | 1,000 | 1,000,000 | 2d |
| 10 | Power P.E.K.K.A | 13 | 8 | 1,150 | 1,500,000 | 3d |
| 11 | Hog Glider | 15 | 9 | 1,300 | 2,000,000 | 4d |
| 12 | Electrofire Wizard | 17 | 10 | 1,450 | 3,000,000 | 5d |
Maxing the building costs 8,590,000 Builder Elixir and just under 16 days of builder time. That is small next to the troop research, so the Barracks rarely holds you back. Upgrade it soon after each new Builder Hall level so you can start researching the new troop.
Troop abilities after Builder Base 2.0
The 2.0 update gave Builder Base troops hero-style abilities. Some work on their own, some wait for you to tap the troop, and you need to know which is which before you deploy.
| Troop | Ability | How it triggers |
|---|---|---|
| Raged Barbarian | Rage: faster and stronger for the first seconds after deploy | Automatic |
| Sneaky Archer | Cloak: invisible to defenses for the first seconds | Automatic |
| Boxer Giant | Power Punch on the first hit; Boxer Block shield | Punch automatic; shield on tap, once |
| Beta Minion | Power Shot: first few shots faster, longer range, more damage | Automatic |
| Bomber | Bouncing Bomb: big bomb that bounces twice, heavy Wall damage | On tap, reusable after a cooldown |
| Baby Dragon | Tantrum bonus when alone; Fiery Sneeze cone of fire | Tantrum automatic; sneeze on tap, once |
| Cannon Cart | Mortar Mode: long-range, lower-damage stationary mode | On tap, switch back and forth |
| Night Witch | Bat Swarm: extra bats for a few seconds | On tap, once |
| Drop Ship | Skeleton Bomb: area damage plus extra Skeletons | On tap, once |
| Power P.E.K.K.A | Overcharge: explosion around her | On tap, once |
| Hog Glider | Stunning Glide: crash stuns the target defense | Automatic on impact |
| Electrofire Wizard | Switch between Inferno and Electro attacks | On tap, switch back and forth |
A one-time ability that you spend in Stage 1 stays spent if that troop survives into Stage 2. The Bomber’s is the exception; it comes back fully recharged. The Builder Base 2.0 guide covers the full two-stage attack.
What changed
- March 30, 2020: training time removed; Builder Base troops are ready instantly.
- May 15, 2023 (Builder Base 2.0): level 12 added with the Electrofire Wizard at Builder Hall 10; troops start at a minimum level when unlocked; every troop gained an ability; fewer troops fit in each Army Camp; the building’s description no longer mentions Versus Battles, which were removed.
- May 26, 2026: an extra Builder Base builder became available (once all Home Village builders are unlocked), so a Barracks upgrade no longer has to wait as long for a free builder.
Builder Barracks FAQ
What is the max level of the Builder Barracks?
Level 12, which needs Builder Hall 10 and unlocks the Electrofire Wizard.
Does the Builder Barracks cost anything to train troops?
No. Training is free and instant. You only pay Builder Elixir to upgrade the building and to research troops.
Can I train troops while the Builder Barracks is upgrading?
Yes. It keeps working during the upgrade.
Why did my new troop start at a high level?
Since Builder Base 2.0, troops unlock at a minimum level so they are useful straight away. Troops you had already researched past that level kept their progress.
