"Crim, stop abusing the earth slimes, and let's go." Crim had found that the earth slimes were just tough enough to protect themselves against his claws. That was perfect for him to practice attacking from different angles.
Clark couldn't get too angry seeing that Crim was somewhat training. The earth spikes that the earth slimes used to attack were too slow to build up so they were too easily dodged. That led Clark to take on the earth slimes using the falling moon pierce over and over. He was able to train his own strength while Crim battles alone. The only one left out was Devi since they were too tough for his teeth to pierce.
Descending the obvious stairway, Clark found a hot room full of lava and slowly moving fire slimes. "Crim, this could be tougher." He knew that Crim could resist flames, but when he looked at the system analysis, he saw that the slimes could spit flames around them. This was a rough area of effect attack.
