Bag of Equivalent Exchange

This is a medium, plain-looking sack, whose only exceptional quality is a teal stripe that runs diagonally around it. It weighs 3 pounds.

Once per day, it can exchange coins from one type to another. For example, 200 sp can be converted into 20 gp upon request. The maximum coin capacity is 1000.

The bag doesn't always get it exactly right, though…

• There is a 10% chance the bag will deduct 10% of the coins in the conversion. From the above example, the 200 sp might come out as 19 gp.
• There is a 10% chance the bag will add 10% of the coins in the conversion. From the above example, the 200 sp might come out as 21 gp.

Coins stored in the bag will make no sound, even if the bag is jostled.
