Yes but what comes out of the weapon is a sort of flame or destructive fire which she can harness. Its in her necklace the same stuff in the weapon is in her necklace, but she can take the mystical flame and tak it out of the necklace and use it.

But its hard to do.

But more like if she got scared so cou;d use raw dark magic (It wouldn't kill but mostly stun or scare someone off)

Her antrual ability is probally she is more agile and more durable then most demigods.
