Chapitre 72: [Arcane Skill: Star Soul Rotation]

"Master, I have instructed Daphne to gather intelligence for you in the Exploration Hall." Teresa said respectfully.

"Here are the five energy essences I collected, costing 300 gold coins."

Although she was curious about why Sterl needed such items, she didn't ask any questions. She carefully ensured that no one else was around to interfere with Sterl's plans.

Teresa speculated that her master might need the energy essences to craft some equipment. She knew that Sterl had recently reached level 20 and completed his class change in the Starfall Wasteland instance. So his equipment probably wasn't fully upgraded.

As for another use of energy essences—to lower the requirements for learning an arcane skill...

Even though Teresa believed her master was destined to be invincible, the idea that Sterl might be dealing with legendary arcane skills seemed like a dream to her. It was simply unimaginable.
