Siłaful Seal

Oh, no. This is quite unfortunate. I thought I could open the lock using the flames made by burning Torge Branches, but it seems several spells have been cast over this box. We'll need magic to open it. No, I won't request the help of a sorcerer. They'll laugh at me and say my magic is a joke, but we both know that's not true. Fortunately, I have a secret stash of Seal Lifting Potion's just in case. However, you have to go get it for me. Bring me the Seal Lifting Potion from underneath a rock in the Shadow Graves.

This is what they call a vision. Bring me the Seal Lifting Potion from underneath a rock in the Shadow Grave.

Hmm, Good job. Fortunately, it's well sealed and hasn't dried up yet. Good. This should work, but this time I won't guarantee how long it's going to take. I'm sure you understand what I'm saying. Don't come looking for me until it's complete. I'll call you when I'm ready.
