Ranger Trainer is an add-on for Dragon Age: Legends of the Three Kingdoms that lets you train a character as a member of the Ranger class. This is done by completing the in-game missions that are set before the player. Each mission consists of a series of challenges that are to be completed. These include tasks such as killing a certain number of people or killing a certain type of person. There is also a daily challenge that is to be completed.

When the player completes a challenge, he or she will receive a reward. These rewards can be earned for various reasons. The most important reason is the completion of the challenge.
