Would you like to make a trade? I think I have something you'll be interested in.

My experiments are very advanced alchemy, and I've been generating a lot of failures. Nothing destructive, you understand; actually a lot of my failures are turning out to be quite valuable items, just not what I'm trying to accomplish.

Anyway, if you bring me Soul Vigor and Life Essence, I will give you the results of any failed experiments I attempt with them. That way, we're both getting something we want.

Player: Accept.

Remember your trade with me?

You bring six Soul Vigors and six Life Essences to me, and I give you any experiments that fail?

Can you show me the material first? My failed results are probably worth more than the Soul Vigor or Life Essence.

Player: "I have them, see?"

I never doubted you. This is definitely the Soul Vigor and Life Essence I asked you for.

In exchange, here's my latest failed test result.

It may be something rare and valuable. Or not. Who knows?
