Aeshma comes knowing Firaga, Cure, and Drain. It also has Ailment Def., which protects it from any status ailment. Like the two forms before it, it has high Magic, Magic Def., Accuracy, and Agility. Its Strength and Defense are mediocre, and its Luck and Evasion are low. Unlike an enemy Aeshma, this one is not immune to physical attacks.
Like its predecessors, Daeva and Aka Manah, it has no life readings. Its age is 10. As such, it has developed linguistic abilities. It claims to be an envoy from the fiend world, a world between Spira and the Farplane.
Aeshma is the Younger Avestan name of Zoroastrianism's demon of "wrath." As a hypostatic entity, Aeshma is variously interpreted as "wrath," "rage," and "fury."
