Currency exchange market

The Currency Exchange is a mechanic that allows players to exchange currency with each other on the open market, paying Gold as the cost of placing orders. The Currency Exchange can be accessed by talking to Alva, after unlocking it through an unknown process.

The Currency Exchange is available in Act 4 through Finn, at least after defeating Lachlann
