Summary
- The Builder's Apprentice is a male non-combatant character in the Home Village. He appears around the Helper Hut once the player has reached Town Hall level 10, and requires 500 Gems to be recruited.
- When unlocked, the Builder's Apprentice can be assigned to a building construction or Hero upgrade that a Builder is currently working on, shortening the overall upgrade time. He can work for one hour at a time, after that he rests for the rest of the workday.
- All Helpers have a unified cooldown timer, which means they all follow the same workday schedule. A workday is 23 hours long, and begins as soon as the player assigns any Helper to a job for the first time in that day.
- For example, at the start, all Helpers are ready to work. When the Builder's Apprentice is assigned to a job, this will begin the 23h workday. When he finishes the 1h job, there will be 22h left on the workday timer. 3 hours later, the workday timer will be down to 19h. If the player assigns the Lab Assistant to a task at that point, he will work for 1h, after which the cooldown will be 18h, not the full 23h.
- The Builder's Apprentice cannot work on Builders' tasks on his own. If the task he was assigned to is completed while he is still active, he will stop work early and cannot be assigned to a different task before the normal cooldown elapses.
- The Builder's Apprentice can only work in the Home Village.
- The Builder's Apprentice can be assigned to work in the Forge.
- Upgrading the Builder's Apprentice (which costs Gems) increases the rate at which he works, and consequently, the amount of time saved every time he is assigned to a task. Upgrading the Builder's Apprentice does not take any time, but cannot be done while he is currently working.
- The Builder Potion and Builder Bite have no effect on the Builder's Apprentice, which means they stack additively (for a maximum of 1+9+1+8=19 times speed).
Appearance
- The Builder's Apprentice dresses similarly to a Builder, with a brighter reddish-brown vest with a pocket in front like a work apron, brown pants without a belt and shoes, and a sandal hat that has a stitch. He wears a backpack with a big scroll in it. He has cyan eyes, orange hair and a side bang, no visible eyebrows like the Builder, and smiling without showing teeth.
Statistics
Profitability
To get an idea of how effective the Builder's Apprentice is, some assumptions must be made. It is assumed that the Builder's Apprentice is used once per day, and the value of the alternative methods used is estimated slightly higher than it is actually gonna be in most cases:
- Directly completing (building or hero) upgrades costs 260 Gems for the first day and 123.333 per day afterwards. For every upgrade (below 20 days, which is every upgrade available in-game), that averages more than 130 Gems per day, which is the amount used here.
- In reality, this is one of the worst ways to spend Gems and should use any other methods to speed up progress.
- Three Builder Potions can be purchased from the Trader every week, for 285 Gems per piece. We assume that all 6 builders have already been unlocked. Therefore, every Potion reduces the overall building time by 54 hours.
- A Book of Heroes can be purchased from the Trader every week, for 500 Gems per piece. We assume that every book is used for a high level hero, reducing the maximum amount of building time for Heroes, which is 8 days.
- In reality, not all Hero upgrades take 8 days.
- It is assumed that the Goblin Builder is available all the time.
- In reality, due to it being an event feature, it might not even be available long enough for anyone to be able to spend all the Gems before the Builder's Apprentice is already more profitable.
By biasing against the Builder's Apprentice, the actual value of him being more profitable than the listed methods eventually is going to be lower than the value shown at the table for most players. Keep this in mind if the number of days for the return seems unrealistic.
In the following table, it shows how many days it will take for the Builder's Apprentice to save more building time than the same amount of Gems used on an alternative method of speeding up builders:
Builder's Apprentice level | Total Cost | Completing upgrades with Gems (130 Gems per day) |
Builder Potion (126.7 Gems per day) |
Book of Heroes (62.5 Gems per day) |
Goblin Builder (40 Gems per day) |
---|---|---|---|---|---|
1 | 500 | 93 | 95 | 192 | 300 |
2 | 1,000 | 93 | 95 | 192 | 300 |
3 | 1,750 | 108 | 111 | 224 | 350 |
4 | 2,500 | 116 | 119 | 240 | 375 |
5 | 3,500 | 130 | 133 | 269 | 420 |
6 | 4,500 | 139 | 143 | 288 | 450 |
7 | 5,500 | 146 | 149 | 302 | 472 |
8 | 6,500 | 150 | 154 | 312 | 488 |
In the long run, using Gems on the Builder's Apprentice will save the most building time in comparison to other ways of speeding up Builders with Gems. It depends on how willing one is to use him everyday. Note that unlocking the fifth Builder is still the most important use of Gems for more reasons than one.

Trivia
- The Builder Potion and Builder Bite are given flavor text in their description for reasons why Builder's Apprentice cannot benefit from them; he is mentioned to be too young for the brew and a vegetarian respectively, which explains why he does not consume them to work faster.

- Out of all the workers in the Helper's Hut, the Builder's Apprentice is the youngest and is the second shortest, behind only the Alchemist.
