I couldn't miss the chance to practice my drawing!
Unyielding earth. Nourishing water. Ride ye the wind. Aether, to me!Y'shtola, Final Fantasy XIV
Though Y'shtola's experience in the Lifestream had deprived her of her natural sight, her powers had grown significantly. She first displays this power during a skirmish with the Illuminati. After some time passes during the duty instance, Y'shtola begins casting a powerful spell, first invoking the elements of earth, then water and finally wind before it culminates in a massive burst of multi-aspected aether, instantly wiping out all enemies currently present, though the blast taxes her and leaves her too exhausted to continue.
In Stormblood, Y'shtola once again invokes this spell at a much greater speed during her battle against Magnai, which she performs after successfully completing the Active Time Maneuver
Spiritual Ray is one of Y'shtola's HP attacks, learned at Level 10. It is identical to its original depiction, though the aether is summoned at opponent's current position rather than around her. It also produces a vacuum effect that draws in her target.
Following her massive rework in Version 1.22, Spiritual Ray was changed to be a much quicker spell cast and losing its vacuum effect.
