Cana unit engaged with an enemy (I.e. in the same area) attach with range an enemy unit in a different spot?
I searched the fora with no success
You can shoot into an obstacle, shoot out of an obstacle but never through an obstacle. If the LoS from the attack goes through, I would then say you can attack on enemy unit in another area and not be stopped by the obstacle (in this case to enemy unit in the same area).
