Enstone (ability)

Enstone (エンストーン) is a recurring spell in the series. It grants the Earth element to physical attacks.

Final Fantasy XI
Enstone is an Enhancing Magic white magic spell in Final Fantasy XI. When under the effect of Enstone, the player or monster will deal some slight earth magic damage following each melee attack. Unlike most Final Fantasy games, ordinary melee attacks in Final Fantasy XI cannot have a specific element, and Enspells do not change this.
 * Example:
 * Player attacks the Eft for 30 damage.
 * Additional effect: earth damage: the Eft takes 12 damage.
