Mysterious Potion

Description
You're going to have a hard time getting the hammer from the ruins. You won't even be able to see most ghosts without the right potion.

Luckily, we have an elf called Truth-Seer visiting. He may not be the best company, but he might be able to make the potion.

Upon Accepting
I'm just glad the elf is on our side.

Completion
You need a truthsight potion? How do you even know what that is?

(He gives you a sharp glance.)
