: Damage values may not be reflected in Free Training.

In Awakening Mode, the stone spins a bit faster, dealing one extra hit or 2 with Useful. The float portion is unaffected in terms of hit count, however.
Using the skill anywhere but at point-blank may cause either the spin or float portion of the skill to not deal full hits as it starts dealing damage the moment it appears.
The float portion of the skill launches enemies, so part of its damage will be lost on enemies that are not in Super Armor or otherwise immovable.
Since the skill appears a bit in front of Aisha, it will always hit smaller shielding enemies from behind.
The additional casts simply allow you to use the skill again with the usual MP cost. These additional casts are not considered part of the same skill use, unlike the extra casts for Dual Buster or Twilight Judgment, and will each individually trigger any "on skill use" effects.
This skill will immediately go on its normal cooldown right after it is memorized, so you can't use it 3 times in a row right after memorizing it. However, memorizing its second or third iteration is possible.
The skill is affected by the Free Training hit count error, with Float dealing 10 hits instead of 9 with the Useful trait.
