"Let's use the Tier 2 Lava Turtle," Jyorta spoke upon seeing the futileness of their efforts. No matter what they did, they were unable to pry open the door and enter the dome. And, even if they were to open it, the Tier 3 Lava Turtle only had the intention to push them away.
Moreover, the intense boiling water it unleashed was more than enough to incapacitate them with enough injuries, a staff would have to save them immediately. Therefore, they were caught in an impasse. They had to do something to change the status quo. Otherwise, they were bound to run out of time.
That was why Jyorta changed their plans. His eyes shone with a cunning glint, for a moment causing the onlookers to flinch. For, it was venomous. It seemed he knew exactly what to do to piss of the Tier 3 Lava Turtle beyond limit and make it lose itself in rage.
