Experience (XP) separates old units from new units, and is accumulated through a variety of combat related actions. Upon reaching certain thresholds, an additional experience star will be displayed in the unit's stats page. A unit may obtain up to 5 stars, though the amount of experience points required for each star increases progressively.
Each star of experience improves a unit's Attack Skill, Defence Skill, Precision, Morale, and Research ability by 1. Additionally, reaching 3, 4 and 5 stars have additional benefits to Strength, Health Points and Magic Resistance. Leaders also gain additional regular Leadership with experience stars. Mages also gain Research Points with experience stars. The table below shows the total bonus to each stat for the XP levels.
