>>95841817 (OP)Thing is. I have no problem with this in Shadowrun, or some dumb grim-dark fantasy setting, or hell, maybe even LotR.
But not D&D.
The problem with a Wheelchair in D&D is that GOD IS REAL AND HE'S PAYING OUT in that setting.
Like, curing paralyzed legs is a fucking level 3 cleric spell. No questions asked. That is straight up something any adventurer has pathetically easy access to. Same with blindness. You should never meet a blind peasant unless they straight up don't have a village cleric, and it's SUCH a good moneyspinner for every church in the setting that I can't believe that one village would be allowed to fall through the cracks like that unless they were some kind of militant athetist isolationist group.
Even if you lost the legs outright, a ring of regen can fix that in a day FFS.
The only thorny issue would be if you were born with a congential defect in your legs, in that case it's gods plan and you should just suck it up.... or find a Genie and a Wish spell. In older editions Miracle might also do it.
The really fucking annoying thing about that specific example is it shows just how fucking little the writer actually plays D&D. Because she (and it will be a she) literally just created a Tensors Flying Disc with a seat on it and then gave it a price 1000% times cheaper.
TLDR: Hovering Combat Wheelchairs always existed in D&D, they were just too expensive for starting adventurers to use.
