Description
You should be happy he's coming, they said. You'll enjoy his company, they said....

Well it's not as if I had a choice in the matter. Finklestein is the Crusade's best alchemist. I suppose I should be honored that he's chosen my post to set up shop. But ever since he's arrived, I've been relegated to collecting various alchemical ingredients.

Say,, how about you give me a hand? Just south of here are some pools that are haunted by spirits of ancient trolls. Collect their ectoplasm for me.

Rewards
You will receive:

Progress
Good day,.

Have you collected the ectoplasm Finklestein asked for?

Completion
Thank you,.

This should save my men some precious time.
