[quote=Judaspriester]According to what I have found in the wiki, it would be best to invest all my Taste of Lacre into him (actually 13), repeat this after I made a few new levels via the snow I still got and then pray that he survives long enough, right?[/quote]Basically, yes. Build up your ToL and then use the "Help me. I beg you." option on the Noman’s Progress card. Repeat until you have enough Noman’s Friend or you run out of materials.
Keep in mind that you need to have ToL of at least 1 to use that option, and ToL resets each time you use it. You’ll most likely need a few hundred points of Noman’s Friend to make it to the second week of February though, depending on when you make the Noman.
