#Also her power slash Aria in general is 100% in tune with her brother Thoma/Aelius

Although Sera is technically a phoenix at her core, she doesn't really have all that much in terms of access to her power. Everything she held to her name as Aria - her ice magic and healing magic, mostly - has been locked down underneath a frozen glacier deep within her, wrapped tightly around her core as Aria and preventing her from getting any too close to any of it. What abilities she does still have are completely minimal and require some kind of aid for her to use them, be they materia in FF7 verses or her vision in Genshin Impact, etc, and are never stronger than the small bits she's able to safely use as a human - totaling out to maybe 3 or 4% of Aria's full strength.

Even so, this naturally makes her skills a slight bit stronger than the average human's, even though it's not much. When casting something like Blizzard, the ice hunk created might be a tiny bit bigger and more solid than say, Zack's, while her healing skills are a smidge stronger in a similar fashion, being able to fully heal certain injuries where others couldn't, but still not much past that. It's enough to be noticed if one is really paying attention, but not much overall; While someone could reasonably tell her ice feels colder to the touch and in a couple inches bigger in formation at best, it's really not all that remarkable, and her lack of skill with other magic types and elements naturally leads to the thought she was likely just focused on the two and failed to train in anything else.

She cannot access anything under the 'frozen lake' without dying, the power too much for her human form to handle, and though she doesn't understand why she would be so afraid of such a thing, even she doesn't know if that death would be her last, a concept that is terrifying and she's done her best to not think of due to a severe lack of understanding. There's no telling what it would take to retake her original form as the Snow Phoenix at this point, but the signs of her being less than an actual human still remain, even if she can't explain them - She's just slowly learning to accept them as just being Sera.
