Suppose I'm playing a character that has a flying speed (such as a Variant (Winged) Tiefling or an Aarakocra) and get critically hit. The DM rolls on the Lingering Injuries table and after rolling a 3 tells me I lose a leg. The table says (emphasis mine):
Lose a Foot or Leg. Your speed on foot is halved, and you must use a cane or crutch to move unless you have a peg leg or other prosthesis. You fall prone after using the Dash action. You have disadvantage on Dexterity checks made to balance. Magic such as the regenerate spell can restore the lost appendage.
If I'm using my flying movement, I know from reading this that my speed isn't reduced (I'm not walking with my feet, I'm flying with my wings). But reading this seems to imply that if I Dash while flying, I still fall prone (and arguably am in worse trouble than if I were trying to run on foot). Is that the case, or am I missing something here?
