Did you bring me some Essence Crystals?

Oh, I hope so!

"I did."

Thanks to you, I will be able to proceed with my Essence research.

Thank you!

"Do you have an Essence Core for me?"

I do, as promised.

If you need more, come back any time. But you need to bring Essence Crystals!

Completion:

Creasione said she would give you an Essence Core for Essence Crystals.

You found Essence Crystals and received an Essence Core in exchange.
