Charisma, along with Stamina, is one of the two basic stats unique to the player. It is a resource consumed by the vast majority of Missions.
Maximum Charisma increases by 3 at every rank until 100, and then by 1 each rank afterwards.
In normal time, it recovers at a rate of 1 point every 3 minutes. Players can also instantly recover all of their Charisma by using 1 Sacred Crystal at the Shrine. In doing so, players retain any excess, though regen will be disabled until it is spent
