Mega Mushroom

 is a rare drop available for looting from Obert of Bones boss. Despite having the material icon, it has no use in any crafting recipe, clutters up your inventory and serves no other purpose than selling it to vendors for 187 triads, a pretty big cash for a beginner, which makes me think that vendoring this item was originally the only meaning of its existence in the game. Yep, just an extra lucky chunk of loot.
