??? Was this from an actual epic or poem??? All I'm finding is a modern published book. I mean yeah trying to see what's "Canon" in mythology is kinda futile* but I don't think we should be citing Percy Jackson and look for camp of demigods.
*Like I'm pretty sure most of the surviving Greek Myths we have today are from Athens specifically which is why Ares is the Worst and Athena is Zeus' amazing bestest kid while Hera, goddess of the sanctity of Marrige, is a huge bitch.
People being like "oh we can just steal from the gods!" Like exhibit A Prometheus. Also why the fuck would a mortal be able to weild a godly weapon. Simply looking at part of a God's true countenance kills you. There is a very clear divide between mortals and Gods of any stripe in Greek Myth, it's a supremely nihilistic mythos. Like Norse myth has their God's getting punked on, China has Sun Wukong who's like the platonic ideal of dunking on Gods. I can't really think of anything like that in Greek Myth, and lots of counterexamples. There's a reason why "hubris" (imagining you could be an equal of the Gods is the peak of this) is one the key essential elements of any Greek tragedy, heck even some of the non tragedies.
To use DnD as an extreme metaphor I'd say a level 1 commoner has more of a chance of surviving literally pissing on an Archduke of Hells Cornflakes than a Greek Myth mortal has of surviving any slightly negative encounter with a God. Like in DnD there's a few CG or even CN dieties who find the cornflake pisser to be hilarious and might be willing to spend some of their divine power saving them.
Again I imagine there might be a chance the DMs are willing to give us options in the faaaarrrrr faaaaaaaaaarrrrrrr future, but don't count on it. After all, DP created this to get a break from DnD.
