Village Helpers guide: Builder's Apprentice, Lab Assistant, Alchemist
Helpers are workers you assign once a day to speed things up: the Builder's Apprentice boosts a builder, the Lab Assistant boosts research, and newer helpers like the Alchemist and Prospector help with resources. Leveling them up makes each boost stronger.
| Helper | Levels | Unlocks | Upgrade cost |
|---|---|---|---|
| Builder's Apprentice | 8 | TH10 | 6.5K gems (all levels) |
| Lab Assistant | 12 | TH9 | 8.5K gems (all levels) |
| Alchemist | 7 | TH11 | 5.85K gems (all levels) |
| Prospector | - | - | newer than the data file |
Get the most out of helpers
- Assign them every day: an unused helper boost can't be saved.
- Point them at the longest upgrade: the boost is a fixed amount of time, so it never makes a short upgrade "more" finished.
- Level the Lab Assistant early: the lab is usually the slowest queue (here's why).
