Jar of miasma detail.png

The jar of miasma is an item that can be obtained from using the unsired, dropped by the Abyssal Sire, on the Font of Consumption. Players have a 13/128 chance of receiving one when doing so. As an unsired is a 1/100 drop, this effectively makes the chances of obtaining a jar 1/984.

The jar can be used on a boss lair display in a player's Achievement Gallery to have a display of the Abyssal Sire. Doing so requires killing him at least once.
