It was specified there are no reinforcements. If they're allowed to bring allies, Vader wins easily; he has the resources of a galactic empire to draw on while Soth has one measly castle. Granted, each one of Soth's skeleton warriors can probably account for dozens of stormtroopers, but sheer weight of numbers still wins in the end.Soth summons his legions to wear Vader down, then takes him out with various magics. Vader puts up a fight and leaves Soth crippled, but Soth is still moving in the aftermath.
By that logic, a stormtrooper could take down Tiamat. Or the donkey in Shrek could take out Elminster.
Force Choke does appear to require sight of the target (even over a video screen) to focus. I'm also not convinced that choking would do anything to an undead creature who doesn't need to breathe.It's said they start on foot. Not where they are.
Soth starts on foot in his castle. Vader starts on foot landing on the other side of the planet, then proceed to force choke Soth. Given the evidence that he can Force choke Admiral Ozzel from on ISD to another, there is a strong chance Vader has abilities that far exceed in range what Soth can do, even PWK.
I feel like you’re not getting into the spirit of the thread!If the stormtrooper is behind the controls of the Death Star, why not? At least they could destroy her material form (I doubt the Death Star would work in Avernus.)
As for the donkey...lure him into a no-magic world and kick him in the head.
