The moment his men fired their weapons, Vicente used one of his special spells and immediately pinned the creature's legs to the ground while increasing the amount of metal on its body.
Doing this to immobilize it, Vicente focused on the creature's wings, the greatest weapon it had to defend itself, attack, and escape.
Not only that but there were no vital organs in its wings!
Using them to increase the amount of metal on it was the best Vice could do without slowing down his men, who were shooting at the creature's vital points.
Even though they couldn't kill it to not interfere with the possible absorption of its pentagram by one of these men, the group unloaded the ammunition in their weapons into that creature.
It was very sturdy, and only by doing so could they wound it enough to create a chance for one of them to kill it!
