not too sure what difference you're hoping for.
Skill AW requirements: Unit must have maxed skill, and unit must be AW'd. (you can check their skill AW once the unit is AW'd, they don't bounce you out like what the AW screen does)
Items required: same orbs as when you AW'd the unit, gold and skill AW fairy Naius.
you can forget about 3rd scene for now since they were only recently implemented in DMM Aigis. so we won't see it any time soon. skill AW will comes first.
