I don't think that it has anything to do with your location, but with your genetics, so that if a Mistborn is born on there planet, and then find a way to travel than they would be able to do it

I would also say that the fight would also depend on what the Radiant summons their spren as, because, if possible, what I would do in this situation is make a spren shield with a weapon as a part of it, like a shield with a spear coming out the top, which would give the Radiant the advantage of having a shield that would be very hard to break, if possible at all and not be a metal that a Mistborn could push or pull, but if that is impossible than ignore what I said because it would be invalid.

What it could be is maybe he hasn't killed the spren he has now. He could have possibly had honor spren or other kind and killed them, and quite possibly didn't feel bad or regret it. I meant to quote @Ookla the platypus but accidentally didn't press the button

It really depends, if it is a 3rd heightened 9/10 times the Mistborn would win, but when it comes to 4th heightened we need to learn more about how the shard-plate works for living Radiants Sorry if someone already said this, I just joined the discussion
