Shillings look like a small pile of silver coins and are located in the resources section of inventory.
How to Obtain
Shillings sometimes drop as loot from chests or as a reward for killing brains. Players who act as official guides in the tutorial worlds also receive a small shilling stipend for the time they spend there helping new players.
How to Use
As of March 2015, the only use for shillings is to pay an android to convert a figurine into either a marble or bloodstone statue.
Shillings are rumored to play an important role in future updates with regard to specialized guild trading.
