As you gain experience (XP) by completing Quests or defeating Monsters, your XP meter will begin to fill. Once the meter has been filled, you will advance in level.

The XP bar is located at the very bottom of the interface and as it is acquired, the gauge will begin to fill with Blue Color. There are a total of 20 partitions in the XP Bar, each being 5% of the Max XP for your current level.

Hovering over the XP Bar will show [Current XP/Max HP of Current Level]. After being defeated, XP that is recoverable from a Soul Healer at the time of resurrection is indicated by a grayed out area of XP on the XP Bar.
