Rotten Mushroom


 * Not to be confused with Black Mushroom.

Rotten Mushroom is a quest item in Diablo III. It is only available during The Darkening of Tristram in January.

It can only be obtained by accessing the Black Mushroom curio in the Labyrinth Level 9, starting the hidden quest for Wirt's Leg (Diablo III) and Royal Calf. Bringing this to Adria's Hut and accessing her cauldron will produce the Witch's Brew.

It's a nod to the quest Black Mushroom from Diablo I.

Item Description
Old Mushroom

''A corrupt stench lingers around this mushroom, as though it is more than mere rot. Mixing it in a cauldron will yield a special brew.''
