- Unique skills (red). These are very rare, special and tied to a certain general. They can not be changed. Very valuable, since very few generals have one.
- Primary (blue). These skills affect the battlefield both in PvP and PvE (for example, these ones can boost your cavalry’s attack power)
- Secondary (green). These skills do not affect PvP, but they can help you build the city or may have some special effects on your city and armies.
All of the primary and secondary skills can be changed in a general’s Skill tab.
