Djinn versus Black Dragons – it’s nothing!

In the campaign for Solmyr, I remember there being a battle with 20 Black Dragons. In walkthroughs, they also wrote that the Djinn would be swept away here and wouldn't even be noticed. But a hundred blue friends, together with a squad of Titans and the Illusion spell, completely refuted this fact :D. Moral: if, in addition to Djinn, there is someone else in the "anti-black-dragon" army, then they can be of great help and are by no means useless (of course, they need to be placed further away).
