When the dragons entered their range, Alexander used Light Spear, and Natalie used her Swift Strike. The skills hit the dragons faces and then smashed a good portion of their bones and scales. It would be too much to hope for that they already had enough strength to kill a dragon with a single hit. Still, they accomplished their goal, and the dragons fell to the ground, completely dizzy and defenseless.
Felipe swung his spear, and another cannon of light hit one of the dragons. In contrast, the others attacked the other beast with bolts and arrows since it was faster than approaching. The dragons eventually recovered from the first attacks. Still, they didn't have the strength to fly anymore after using their flame attack and getting hit like that. Eventually, the damage caused by the soldiers, barbarians, and mercenaries piled up, and the monsters stopped moving.
