Each Builder Hall raises the Machine's cap. The table shows the Builder Elixir and time to climb from one cap to the next, counted from level 1 (the 900,000 repair is not included).
Battle Machine max level by Builder Hall: BH5 5, BH6 10, BH7 20, BH8 25, BH9 30, BH10 35.

Electric Hammer unlocks at level 5 and moves up one ability level every 5 hero levels, to ability level 7 at level 35. When you use it, the Machine is stunned for a moment, recovers health and lands 3 boosted hits.
The ability charges while you wait. Every deployment starts at charge 1, and each extra tier takes about 13 seconds. At ability level 7, charge 3 heals three times as much as charge 1 (3,300 vs 1,100) and each boosted hit does about 2.3 times the damage.
From hero level 15, charge 2 hits up to 2 targets and charge 3 up to 3. Damage drops by 50% per jump on charge 2 and by 30% per jump on charge 3. Below level 15 every charge hits one target.
| Ability level | Charge 1: damage per hit / heal | Charge 2: damage / heal · targets | Charge 3: damage / heal · targets |
|---|---|---|---|
| 1 (LV5) | 432 / 800 | 702 / 1,600 · 1 | 972 / 2,400 · 1 |
| 2 (LV10) | 480 / 850 | 780 / 1,700 · 1 | 1,080 / 2,550 · 1 |
| 3 (LV15) | 528 / 900 | 858 / 1,800 · 2 | 1,188 / 2,700 · 3 |
| 4 (LV20) | 576 / 950 | 936 / 1,900 · 2 | 1,296 / 2,850 · 3 |
| 5 (LV25) | 624 / 1,000 | 1,014 / 2,000 · 2 | 1,404 / 3,000 · 3 |
| 6 (LV30) | 672 / 1,050 | 1,092 / 2,100 · 2 | 1,512 / 3,150 · 3 |
| 7 (LV35) | 716 / 1,100 | 1,170 / 2,200 · 2 | 1,620 / 3,300 · 3 |
Damage is per boosted hit on the first target. The Clash of Clans Wiki lists 716 for ability level 7, charge 1; 600 damage per second at 1.2 seconds per hit would give 720.
From level 26 the two heroes cost exactly the same per level: 19,000,000 Builder Elixir and 30 days for the BH9 step (25 to 30) and 21,500,000 and 35 days for the BH10 step (30 to 35).
| At level 35 | Battle Machine | Battle Copter |
|---|---|---|
| Hitpoints | 5,380 | 3,456 |
| Damage per second | 290 | 193 |
| Targets | Ground, melee | Ground and air, 7 tiles |
| Best heal (charge 3) | 3,300 | 1,950 |
The Machine is the tank: more health, more damage and the bigger heal. The Battle Copter flies, so ground traps and ground-only defenses cannot touch it, and it shoots from range. Upgrade the one you take into most attacks first.
From Builder Hall 6, Builder Base battles run in two stages, and you pick one hero machine for each. Supercell's rules:
On Dark Knight #82GY00YYQ my Battle Machine is level 35, maxed at Builder Hall 10. In stage 1 I fire Electric Hammer (ability level 7) at charge 1 instead of waiting for a higher charge. If the Machine runs out of health before stage 2 begins, my level 22 Battle Copter struggles against maxed BH10 bases, so I plan to upgrade the Copter sooner rather than later.
Builder Elixir, upgrade time, Builder Hall needed and Electric Hammer level for each level. Level 1 is the repair.
