Experience level indicates the power of a unit relative to other units of the same type. Units advance their experience level by gaining experience.
A hero's experience level is expressed on a scale from one to six. Other units have only three levels: inexperienced, experienced (denoted by a silver medallion), and veteran (denoted by a gold medallion).
When a unit attains a higher experience level, they receive additional abilities and/or increase their stats. Heroes are able to choose how their abilities and stats improve, but other units are improved based solely on their unit type. A hero's upkeep increases by 
2 when they go up one experience level; other units upkeep remain the same regardless of experience level.
Difference from Unit Level[edit | edit source]
Experience level is easily confused with unit level, though they are quite different. Some of the main differences are
- Unit level describes a unit's strength relative to other unit types; experience level describes a unit's strength relative to the same type.
- Unit level only applies to non-hero units; experience level applies to all units.
- Unit level never changes; experience level may increase as experience is gained.
