Alfheim is unlocked when you reach Apex level 1. To reach this area click on Alfheim or go through the Apex Mystery quest window by clicking the button GO. In this area players can earn points for Apex Ranking or beat the weekly Apex Boss for various rewards. When enough points are collected the Aura event opens. For 30 minutes Crystal Mine orbs spawn at certain locations that players can collect. These orbs do not cost stamina to collect and is a great way to earn more points without spending stamina.
