Nest of Dragons, Fool's Path | Alin

Attack the enemy city North-East of your position. Take it over and free the dragon Thuran (1). You have to quickly train some air forces and send them to save dragons to the West (2). Thuran himself is quite a powerful unit so just give him support of 2-3 others and go for it.

Enemy will use the Dark Terror spell that deals damage to your units while they're away from your own territory. Use your newly acquired dragon unit to attack enemy caravans trading with the oasis (3). It will lure the enemy forces out of their base and allow you to easily take care of them.
