Leveling and the accumulation of experience points are accomplished in several ways including defeating monsters on the field, quests and the acquisition of special experience scrolls which provide immediate experience points, not to be confused with special scrolls which provide a boost in experience points gained while fighting monsters.

Each level requires a certain amount of experience points to complete and pass onto the next level and from level 1 to 300 it only becomes more difficult.

Players should focus on fighting monsters close to their level for the most experience, as fighting monster to far above them or below will not be beneficial and may even hurt their leveling speed. Monster names will change color based on the player's level to help guide the player to which monster they should be fighting appropriate for their level.

Gray	130 or more levels lower	No Experience Gain
Blue	129 to 21 levels lower	+20% From Base EXP Of Monster
Yellow	20 to 11 levels lower	+50% From Base EXP Of Monster
Purple	10 to 0 levels lower, 0 to 3 levels higher	+70% From Base EXP Of Monster
Orange	4 to 5 levels higher	+50% From Base EXP Of Monster
Red	6 or more levels higher	Only Base EXP Of Monster
