Chapter 691: I am not worthy

Sister Orb then explained, [First, you'll need to increase the size of the Soul Gem Dimensional Realm. That means expending 8000 Destiny Points for it.]

"Are you telling us that the perk that comes with the next Dimensional Realm upgrade is an increase in size?" Rean asked with a hint of confusion. After all, Sister Orb never told them what the Dimensional Realm upgrades would give them unless it was some kind of reward. 

However, Roan shook his head, saying, "That's not a perk. The Dimensional Realm would increase in size regardless if it gains some new ability or not. In fact, the Dimensional Realm had increased in size during the last two times we upgraded it."

Sister Orb confirmed Roan's words, saying in response, [Correct. I still can't tell you what its new ability will be. However, an increase in size always happens regardless, so it's not a secret to start with.]
