An unsired is an untradeable item dropped by the Abyssal Sire. They are to be placed at the Font of Consumption, which dissolves it, but gives the player a reward in the process.

It cannot be deposited in the bank – attempting to do so will result in the chatbox stating A magical force prevents you from banking this item!
, Note that if a player has a bludgeon piece, they will not receive duplicate pieces. For example, if the player obtains a bludgeon axon and their next unsired rolls into the bludgeon table, they will be given a bludgeon spine or claw instead. However, if the player places two unsired at the same time, it is possible to obtain duplicate pieces.

When the rarities and prices of each possible tradeable reward is taken into account, the theoretical value of an Unsired is 7,010,307.
