Ambushes

Most units can hide from the enemy when they occupy certain types of terrain, including fog, caves and forests. Units that are hiding will have a small blue eye icon appear next to them (as well as on the unit’s portrait), while the enemy will see an empty hex. Enemy units that are hiding can be found by moving a unit next to them, or by using a spell that reveals them.

Units that would be hiding if they were not spotted will have a red-eye icon instead of the usual blue one. If, when moving, a unit encounters a hidden enemy, it will be ambushed, even if moving to a hex adjacent to that enemy. If a unit is ambushed, the enemy unit will attack automatically, interrupting the unit’s movement.

After being ambushed, your unit will still be able to attack during that turn, provided there is an enemy within range.
