Well thanks a bunch. You just saved me a a lot of trouble of trying to figure out which feats are legit. Previously, I had Emma at large building level because I scaled her to Vita, who lifted the Vermillion Palace into the sky with a forbidden spell that all Hexen Clan witches can learn, so she is at least capable of it. Then I scaled Lulua to Mana, whom is continent level because the ruins she operates, Orthogalaxen, is confirmed to be supporting the whole continent-sized nation of Arland barring Arklys. I was convinced Lulua had this until I discovered Ishmelga's planet-busting S-Craft, which threw a wrench in my analysis. I was even starting to suspect the Sephiroth Supernova paradox at play there.

Your analysis is very solid. Yeah, I saw Sterk create stars in his ultimate, so I'm convinced it's legit alongside Kurt's S-Craft. With that in mind, I'm going with the highest possible scaling imaginable for them since I don't want to lowball any of their feats.

However, there is one more outlier I need to investigate, and that's whether or not Lulua is multiversal. The reason being she was able to synthesize some items that allows her to cross into parallel universes, and in the bad ending, she can transfer her Alchemyriddle to another parallel universe Lulua. I have never seen Emma do anything like that in the Cold Steel games as far as I know. If confirmed, then Lulua clenches victory here since her alchemy magic surpasses even Emma's. This one requires time though because I have never really reached the end of the game yet (I only did deep research).

I should also point out that Lulua is no slouch in the status affect department either. Her item traits, even at higher alchemy levels, are devastating. Some of my friends even called her alchemy "broken".
