Charisma is an attribute that influences your ability to lead troops by boosting Morale, build cheaper with Trade points, bring more troops at the start of a match via additional Army Setup points, and expands your Command Radius inside which Conversion can take place and gives units under your control a Command bonus (increased Movement Speed and Combat). With each Trade point you consume ~ 0.97% less resources for building, researching, or, training troops. The Trade skill increases with a falling function. If you have less that 5 charisma you have to pay additional resources.
For each Charisma Point you get:
- +1 Trade skill
For each 2nd Point you get:
- +1 Morale
For each 4th Point you get:
- +1 Army Setup Point (Up to 8 at 28 Charisma)
- +1 Command radius (but, sadly, it doesn't increase at higher level)
