can a creature be knocked prone while swimming/underwater (not standing on the seafloor)? What would the condition of being prone in the water represent? #dnd #dnd5e Swimming doesn't make you immune to conditions, I'd rule being prone while swimming as being all spun around and off-kilter. You spend half your speed on your turn to right yourself and get your bearings.
