where to get ripened mushroom

you can find ripened mushrooms in map 2 and map 3 kill the altaroths that are belly fully of blue mushroom gathering points, the orange mushroom gathering points are not the source of ripened mushroom, only the blue mushroom gathering points are the 1s containing the rippened mushroom

just wait for the altaroths to eat the mushroom then kill them and you will get the ripened mushroom

TIP :  doit fast because the altaroth can consume the limited amount of blue mushroom gathering points

reminder: blue mushroom gathering points not the [blue mushroom] item

blue mushroom gathering points = mushroom gathering points that are colored blue
