I'm thinking those items you acquired for Lotwil are going to be the least of our worries, <name>. On the other hand, you've proven more than adept at the sciences Lotwil holds sacred, so how about helping me out?
I need an invisibility potion and a healing potion; both might come in handy real soon if he pulls this off.
In return, I'll give you this recipe for a potion I've been developing while learning from Lotwil. It's based on some of the research he's been doing here in the Badlands.
I mean, thank you, <name>. These will be helpful while traveling through the Badlands.
