Combat wheelchairs

[KorvinStarmast]

I don't know, I remember a character not being killed after he mentioned to the GM (after he rolled damage) that his character is clearly stated on his sheet to be 4'9" and the trap that was supposed to shoot him in the head was described to be 5' high.

*golf clap*

The assertion(which you answered) that

there is no mechanical difference between being 5' tall or 7' tall

requires a suspension of disbelief a bit more robust than I am usually able to reach.
(Someone else also noted the jumping rules ...)
