When Kyle reached the fourth room, he found a bunch of gorillas, which were actually not Ore Fiends.
These were just underground gorillas with Earth Affinities.
They were probably the reason why the Ore Fiends in the last room had the appearance of gorillas.
Most of the gorillas were in the Early Second Realm, but some of them were in the Mid Second Realm.
They were a bit faster and fought with a bit more intelligence, but not a lot more.
This room almost played out the same way as the last one.
In fact, despite the increased Realm of some of the gorillas, it was even easier.
The reason was simple.
Fear.
Ore Fiends didn't feel fear. They just emulated whatever behavior they saw.
Yet, these were actual beasts, and they had emotions.
When Kyle had stepped in, most of them were intimidated by him.
For some reason, he seemed really scary.
However, the gorillas could also tell that Kyle didn't have a lot of Ether in his body.
