Charisma

From Haelrahv Wiki

This is the measure of your characters personal charm, which does not necessarily include physical appearance. A high charisma will aid in getting more from selling commodities or items, as well as getting discounts from certain stores. This also has an effect on spellsongs and is paramount to many Guardian abilities. Along with all that, this stat contributes to your essence. Unlike other games...this is not a stat one should ignore!
