Chain Quest: Please help me!

"Everyone is safe for now." Randolf paused for a moment then he added, "You're all quite lucky that you survive from the impact despite how close you are from the collision of the two tier 3 spells."

"Yeah..." Lumilia knew that it wasn't luck. That powerful impact would kill them if not they would receive heavy injuries that could be healed by a tier 3 healing spell.

If not for Cluster they wouldn't survive with little injuries.

So this was the reason why Souta was interested in Cluster's origin. She has a mysterious power that was hard to explain.

"I'll tell you that I couldn't cast another spell. I used all of my mana." Randolf said to Lumilia while looking around.

That tier 3 spell consumed most of his mana. Although that spell was his inner spell he still consumed most of his mana in his mana pool. His mana pool wasn't as vast as those veterans. He was just a first-year student and had a lot of room for development.
