Special properties of units and heroes.

1) Evokes pity. Attacking such creatures lowers morale and also creates a chance that the opponent will hesitate to attack them, which is higher the lower the morale. 2) Dense Fog. Can create a cloud of dense fog. Units within it receive no benefits from their hero. 3) Astral Shift. Can move through the Astral Plane and merge with any army. It can also leave the battlefield through the Astral Plane (for example, this could be added to Angels).
