That would be the Variant option for human in 5E, , I believe, which means its up to DM discretion.
So, it inherently isn’t a super safe option if you’re relying on that feat for some reason if you’re a nerd who just workshops builds at various levels for fun.
The last group I was with ran mostly DND 5e. However, our DM needed a break, and another player took up the reigns for a Star Wars Table Top.
It was not serious. Homebrew and the rule of cool made it a blast - Think Guardians of the Galaxy comedy in a Star Wars wrapper.
The DM for that set goal posts. Like around a certain level, force sensitive classes would get their first light saber.
My character was a bounty hunter who finally got his Mandalorian armor where I could customize “components” like a hand mounted flame thrower, or a shoulder cannon, or what the fuck ever. We spent more time dissecting statistics to get it balanced than anything thematic.
Totally home brewed in that system.
I think that was my best table top experience, and I’m an old school DND nerd. I feel like some days I can barely do my job, but I can quote how THAC0 works on a whim.
I don’t understand statistics unless dice are involved, and no that does not extend to gambling dice games. Utterly useless, but I can go into an ADHD hyper focus on anything that is not actually beneficial to my life in a tangible way, lol.
