A mushroom-loving man in Capstan is not too happy about an invasive species of fungi destroying the edible crop at his favorite spot. This spot is in Eert Grove, which is the mini-dungeon near Goldpaw. Travel to that city and look for the trail northeast of it that will lead you to Eert Grove. Once inside, you will see a tainted sporcino, which are the little mushrooms a mumshroom will spawn. It will run off and you will have to track it down, which is to the southwest corner, where the mumshroom will be waiting. Abnorma is level 37 and isn’t any different than a normal mumshroom, so you’ll need to watch out for the gas it releases after charging up, as well as the sporcinos it can spawn. You’ll receive 5 Soreaway Sweets for felling the mumshroom, as well as the other rewards when you go back to Capstan and speak to the man.
