The Origin abilities are weak in their initial implementation on purpose, I feel.

Red Prince's is hopefully a precursor test for a magical version of Overpower. It would suck if ONLY he had this type of skill, practically forcing him to be a mage.

Lohse's is the perfect example of a "bad" source skill. It can affect allies. It only works when the armor is gone. It does no damage to strip even 1 point of remaining armor. It is the mage class in a nutshell: Useless until the armor is gone, but still able to screw over your team.

Ifan's is weird because it lacks armors AND that he spawns in as a Wayfarer. The class seems poorly suited for his background. He should be a shadowblade of sorts with Finesse and Summoning.

Sebbi's is the only one that makes sense, but doesn't fit well with her class. She's a rogue. They have 500+ ways to remove debuffs through Adrenaline, Hasting Themselves, etc.
