Farmers are the pillar of colony, its role is to travel the world in search of food.
Farmers are not good at fighting but their ingenuity will enable them to develop the best strategies to harvest efficiently and sustainably.
Even if they are not designed specifically for that, their talent in exploration is not negligible. They are not afraid to move away from the base to look for new places of interest and perhaps more profitable harvest sites.
The farmers are rather resistant to their environment but beware, in times of famine, it can quickly become the ecatombe in their ranks.
