Charisma is a statistic in EQOA primarily associated with healing efficacy.
Charisma increases the effectiveness of healing spells - although with diminishing returns as one's Charisma statistic increases. Charisma generally increases one's heals by 25% of the charisma statistic. Consider the following example, based on the Druid spell Celestial Healing:
|Charisma||Heal per tick|
Thus, Celestial Healing, which heals a base amount of 650 HP per tick, is increased to 800 per tick with a Charisma of 600 (150, or 25% of 600). And accordingly, increasing one's Charisma from 550 to 600 effectively only contributes 13 point of heals, or 1.625% of the maximum healing of Celestial Healing - thus only in the most extraordinary circumstances is such a Charisma score worthwhile.
Charisma also effects the duration of charm spells, for Enchanters.
