everyone ranged units have to move forwards because if enemy reinforcing ranged units are attacking you while you are destroying the castle your units cant hit them so they move forwards so that you have a clear shot at them so in fairness your ranged units move forward

polb to beat a black goblin you have to use either an angel (titan) or a dragon (titan) i recommend the angel

hint for the third challenge: use tower skill to attack lord baal
