Amalya moves forward shield up towards the Red Iron Ants in front of her in the tunnel as the main tank of this team. It is her responsibility to generate enough aggro to focus all the enemies on her. The Red Iron Ants have all their information available. It is one of the benefits of an infestation all monster information is freely available. Amalya is thus better able to understand the enemy and she must do. Behind her, Tyr and Omnicornlyre are ready waiting for a signal before they move in. Of course, Tyr could overpower these few drones but this is the perfect time to build teamwork which they will need to defeat the boss. Tyr doesn't want to cripple their progress by making them too reliant on him.
