The attack that they created were miniature star cores that would explode on the impact of a hard surface. There were five small meteorites created that were shot towards the portal.
Each meteorite had slight deviations to hit different ranges of the path. They didn't even make a practice shot, but Martha was confident in being able to pull it off. Her path of Combat and Foresight had improved during the training, and shooting the arrow was now easy.
The meteorites shot through the distance and quickly zoomed past the many Feather Folk who was waiting to send one more message before heading back to the Temple.
Finally, the Feather Folk watching over the portal saw it flying by. It flew straight for the opening of the portal.
On the other side of the portal, the armies continued to hastily position themselves near the exit where they would wait for Heralcus to emerge on the other exit.
