You can attack Crazy Lobos by clicking on the map or other players via the button next to the map.
On the map, choose county marked in light blue and choose one of grey areas. Click on the “Start attack” button to get to the setup for your battle.
The units of your opponent are shown on the opposite side, your positions are marked in green closest to you. On every spot you can position one type of unit and however many nomads you want to position (use the slider to change the amount). If you would like to use more than one unit type, make sure that you do not position all your units on one spot when starting to arrange the fight.
As soon as your line-up is ready, click “fight” to start the battle.
