One of the simplest ways to increase your skills is by trading in materials that can either be found or crafted using currency collected during quests etc., but another way of increasing your skill caps is by completing daily challenges that are available on the main screen once log in. This daily challenge rewards players with 400 currency so if you complete it every day then this currency will accumulate over time and it allows players to improve their character more than usual since they can upgrade existing abilities at any time instead of waiting until next level up or next rank!
