"but then Chelia came along and broke that rumor"

Wrong. Unless Chelia learned Sky God Slaying Magic prior to turning 8 years old, which I highly doubt. Did you forget the 7 year timeskip?

Also everything Sane said, except for one addition.

That Chelia can heal herself is irrelevant to this discussion for two reasons:
 * 1) Simply being on the battlefield and fighting, even if it's only smallfry that can't even put a scratch on her, will prevent her from healing anyone, since she can't fight and heal at the same time.
 * 2) She can't heal herself if she's knocked out, out of magic power or dead.
