Vendor Currency

Ergo

Ergo is the currency needed to exchange for the boss weapons in Alidoro’s shop. For each map, you can only obtain 1 type of Ergo. However, after completing the game you are able to replay the story with all of your obtained items, as the game has multiple endings this allows the players to experience all possible choices and endings. Learn more about the replayability and new game plus system.

How to Obtain Ergo

To obtain Ergo you have to defeat a boss, it is important which boss you defeat as each boss has it’s own specific Ergo which can be exchanged for a boss weapon or an amulet in Alidoro’s shop.
