Charisma

Charisma is one of the 6 main stats in Shilla. It mainly reduces item prices at shops. It also helps get into Elven Village if you have a decent amount of Elf kills. It also adds to your total Mana value, and adds to your Wall Score.

Other then that, there isn't much other use for it. If you are a Mage, and in the Wandwielder specialty guild, Charisma will also add to your attack spell damages.
