To What?
After coming to understand all of these things, Sylas had also come to understand that the reward he had been given was no simple reward.
Without such a Fusion Crystal, comprehending more than one Comprehension was impossible—as far as he knew. If you were unlucky enough to have grasped a mediocre Comprehension first, then you would truly be screwed.
Though, maybe Sylas was thinking too much. Like Cassarae had said, Comprehensions were rare to the point she hadn't run into anyone with one. Sylas had come across a few he thought might have one, but he never got the chance to confirm one way or another.
Even if he felt the way he completed this Quest was less than satisfactory, he couldn't argue with the results.
For now, he wouldn't use the Crystal. His plan was to see how much he could improve his Dormant Comprehensions first before he took action.
