I want to learn Alchemy from the Alchemist in Harbor Town, but he tells me that I must first learn basic Alchemy from his assistant Garth. The problem is that Garth won't talk to me. I did fight him briefly after I followed him for Weasel for the Brugelweed quest, but I'm not sure if that has anything to do with it. I also tried a joke spell, but he still wouldn't talk to me. Anyone else have this problem?
