As the title asks. Do they have dragon like immortality? Jus ta very long lifespan? or are they closer to mortals?
I’ll get back to you when I ask one in real life.
Edit: On a serious note, are half gods like “Hercules” immortal from their full god parents?
In the Disney movie, Hades sent those two failure demons to posion baby hercules, so he would lose his immortality.
You know who else is immortal?
Tolkien orcs.
It’s interesting that Gygax made the jump to “shortest lifespan” like he did, for them.
