Skill:
mole
Allows the hero to move underground, i.e., completely unnoticed.
However, the hero becomes visible when passing through a dug-out burrow (while searching for the main artifact). If a mole is encountered during digging, a battle will occur.
As the skill level increases, the speed and level of creatures that can be taken along also increase.
from level 1 to 3.
Moles can attack creature dwellings in a town and destroy them, but their actions will be met with resistance from the inhabitants of that dwelling, and after a few cycles, the garrison will intervene. And there may not be enough time to complete the destruction.
If the garrison has been defeated, the number of cycles will no longer matter.
