Lunatic Sorcerer Ur

You broke the dagger's seal, but can't summon the soul that's trapped in it?

That's quite annoying. Well, you are in luck, because I happen to have some free time. Otherwise, I never would have accepted such an absurd request. I will give you the Soul Orb that's linked to the soul trapped inside that dagger. You should be able to free the soul with it.

The orb's magical powers are limited, so you must wait until it is recharged after using it.
