Charlemagne is the final Charlemagne kingdom's prestige hero and requires 500,000 prestige to unlock.
Unit Type - Triarii: High Critical Strike Rate, High Block and Dodge Rate. Gambit - Divine Intervention: Attack a single target for gambit damage and restore 100 morale to himself while also reducing all damage Charlemagne receives for 1 turn.
Charlemagne has High stats all around but comes in 3rd or 4th in the Tactics rankings. His gambit makes him a fantastic "support" gambit hero in combination with heavy hitters like Ogier the Dane. Bring in a flag bearer to counter enemy flag bearers and he'll unleash gambit after gambit while tanking a massive amount of damage.
