Resources must be obtained so the castles can be improved and upgraded. The hero s tasks are many. Combat occurs on battlefields that resemble the terrain where they are initiated. If a castle is being assaulted, then the castle walls and fortifications are present. Ranged attackers will fire with impunity so long as there is no enemy adjacent.
Some units have the ability to cast spells.
Each unit has a native terrain type, and they receive combat bonuses for battles fought on their terrain. Heroes not only add modifiers to the attack and defense values of the units, they can also cast powerful spells. At high levels, it is possible for strong heroes to dispatch formidable armies by virtue of their magic alone. All combats are fought until one side has no units remaining under their control, or one hero flees or surrenders. Ye should be aware that when Lord T was Regent of the Interior, he had all the battlefields clear-cut, making them much larger than they used to be.
