What Kafan was in doubt was how far the Wonder Beasts would go before they turned around and run back to the tower. At first, there wasn't really a need to check that since they had the strength to kill the Wonder Beasts at the end of the Chaos Laws and Energy waves that the beasts followed. However, with that teleportation ability that didn't seem to use Spatial Laws, things got trickier.
After the experts reached the point Kafan mentioned, he gave the order. "You will only fight them for twenty seconds. After that, I want you all to retreat. Those with supporting type Domains will stay on the back and far from each other. Use your Domains to help everyone flee. The Wonder Beasts will pursue us, and the other Wonder Beasts in the tower's range won't have time to notice anything. Alright, start!"
