I was just messing around when figuring out Abyssal clears on Emblem Ike and I found out this unit is just omega carried by Great Aether, and so he actually cannot do anything if he is not able to proc Great Aether attack. Though I guess this will only work if you have a Mythic Veyle that has a really high res stat in your team or your fav unit is a dragon that uses scowl A skill.
