This super healing magic is pretty lame, but the saving grace could be what was left unexplained by Nakaba.
Remember how Elizabeth broke Zeldris curse on Merlin that was placed with the Demon King's power? Or how she broke a curse of silence on Diane that was placed with Monspiet's commandment by 4C-Mael? These curses are said to be absolute and only breakable by the Supreme Deity, so I've always wondered how Elizabeth broke two of the Demon King's curses with her own strength. Because it's quite impressive for her to do this when they're said to be absolute and Elizabeth is in a nerfed form.
Perhaps this ''super healing magic'' is kind of hax? Maybe she's able to heal any ailment, curse, weakening effect or anything disadvantageous to someone? She did use a spell to reject demon miasma, which seems to be corrosive and kills anyone that isn't a demon..
I'm probably overthinking it and it's nothing this hax or interesting.
I mean on the bright side at least she kept a magic, Meliodas lost his
What did Elizabeth even do with this ''super healing magic'' anyway? Heal some fodder soldiers during the war? Unless it's what I'm thinking above, its honest shit lol.
Elizabeth's super healing magic is a total joke. It's kind of weird that she even has a personal magic power in the first place since it seemed like the goddesses only had Ark + sometimes a Grace which had been granted to them by the SD.
Gelda's magic being unknown(which means that Nakaba didn't want to reveal it just yet) is interesting since it could mean that she's going to be relevant in the sequel at some point. Either that or her kid is going to have a similar power and Nakaba wants it to be a surprise.
Dubs is the only giant seen so far who has a personal magic power rather than just Creation, although you could make a case for Drole's Ground being its own thing even though it's basically the same power. I wonder if this could have something to do with how Dubs is apparently very small for a giant, something like his development stopping before he became a full blown giant so he instead awekened a different power.
Well Elizabeth should be the exception since she is the SD's daughter and should inherent some unique/special power. In fact, she's already shown to have unique powers with her light wings and animal ark that the archangels do not have, but it hasn't been explored or defined.
I don't think that's the result of laziness. The SD and the DK are the gods of light and dark respectively, so it's fitting that their powers are basically equal but opposite, kind of like 1 and -1. This also extends to their clans as a whole to some extent:
The demons are mostly physical fighters while the goddesses are mostly magical fighters.
The demons die if their hearts are destroyed while the goddesses can survive as spirits even if their bodies no longer exist.
Mel and Chandler's version of Full Counter affects magical attacks while Estarossa/Mael's version of Full Counter affects melee attacks.
I kinda wish Nakaba would have extended this theme to Mel and Elizabeth as well. If Mel's power is to destroy anything, then Elizabeth's power could have been to heal anything. I guess it could still be something like that but so far it just looks like normal healing that just happens to be very powerful.
It would be interesting. Perhaps, with my ideas above, Elizabeth's magic could be capable of restoring anything to its original state, even through powerful curses and ailment, whereas Meliodas magic is capable of destroying anything even if its behind a form of protection or resistance.
Elizabeth's magic would basically be Orihime's healing from Bleach, which I could accept with how hax it is. But if it's just.. generic healing that's slightly stronger, bruh..
