Trading allows you to send and receive monsters to other players. Trading will help you to complete your monster index or obtain some of the harder to find monsters. The current system allows you to set up trades so that even when you are offline other players will be able to complete your trade if they meet the requirements.
Before setting up or searching for monsters to trade, you must first add them to your Wish List. Monsters can be added to your Wish List directly from your Monster Index or from the monster lists or indexes of other players.
