This is your first spawn.
This is your enemy's spawn.
There are 2 types of building: Spawn and Tower. Spawn produces units. Tower attacks enemy units. Unflagged buildings are non teamed buildings. Therfore, these buildings won't attack the other.
To send unit to other spawm, drag your pointer from your building to the target building.
Selection of multiple spawns are done by dragging the pointer over all of the desired spawns.
This is energybar. This bar will be filled with the souls of the killed enemies. Once the bar is full, you can cast magic to your enemies.
