@endbringernick: Her law allows Hadou Gods to coexist, it doesn't mean she can't fight. Not only that but she has that thing about "if you touch her, your head gets cut off." so she does have fighting stuff.
@dyzaghost: Her death curse here is probably useless here as I recall Othinus is a ranged fighter.
Not only that, but that's all her Law does, allowing the coexistence of Hadou Gods who would otherwise impede each other's existence. Also, In-Character, Marie has never hurt anyone unless she was inside Ren's scythe.
So, Ren or any Hadou God wanting to protect her needs to be here. Marie has absolutely no combat feats.
