The idea of there being wheelchairs in a medieval fantasy setting isn't the problem, it's the idea of crippled adventurers and that evil necromancers and dragons would make their lairs conveniently wheelchair accessible is what's retarded. There's a reason why standard adventure gear for all classes includes lengths of rope and a grappling hook. What are they gonna do when they encounter a beholder? Those things use their innate levitation make their lairs a series of vertical shafts specifically to foil would-be intruders.

Beholders are extremely paranoid and will have a trap against anything that exists in said universe. So have fun dying to the wheelchair trap
