So I could use some help finishing off my character. I’m playing Adam Winters, the Chosen One

He is a descendant of Cain, the first murderer. Abandoned at an orphanage as a baby he’s was adopted by the Winters who raised them as their own.

He got accepted to Boston University with a sports scholarship. The night before classes start he sees some guys mugging some old man. He goes to chase them off but they are hideous monsters. The old man gives him a weapon and tells him of his “heritage” then flees into the night.

Because of all of this Adam is late for class sign up and is forced to take a weird sounding course of paranormal lore. This is where he meets our flake and expert.

So basically what I need help with is choosing my weapon, and maybe my hero and doom tags. I’m thinking for hero tags maybe “you are the champion” and either “end of monsters” or “you can save the world”.

Me and my DM agreed that a good destiny would be for me to defeat Cain. Would that require me to take nemesis as a doom tag?

For doom i was also thinking ” you can’t save everyone” and either “hosts of monsters” or the end of days.

Any help would be greatly appreciated
