If there was one thing Zeras could learn from climbing the tower, it was knowing well that the power levels running through the towers were incredibly strong and beyond his imagination.
Every floor presented something unpredictable, which gave him the benefit of doubt and also informed him of his ability to be a little more imaginative and believing.
On this floor, he was willing to make a deal with a dark shaman, who had almost hesitated in the first place, and Zeras was the one being offensive in such a situation.
It was because he believed the shaman possessed the power.
The only reason why Zeras had made such a deal was that he knew well his travel through the tower was now over.
What he wanted was not something that he could find by going up the floors.
It was something that had been in his grasp from the beginning, yet he had failed to grasp it, but now he could sense it.
