The Demon Hunter's Handbook contains a trait called Runaway Slave. It contains the text, "You...gain low-light vision 10 feet. If you already have low light vision, its range extends by 10 feet." How is this possible? Low light vision doesn't have a range. Low-light vision means (basically) that light levels are one higher for you for as far as you can see. So a torch is 20 feet of "normal" light and then "dim" light for 20 more feet. The way I understand 'Low-Light Vision" it means that a character with this ability would see 40 feet of 'normal' light. So how does giving someone 10 feet of low-light vision do anything at all since the normal light goes out past 10 feet already. And if you already have low-light vision, its range is your eyesight, so does this trait let you see further than you already can?
Presuming that it just adds 10 feet to the effective light level, then a candle which provides dim light for 5 feet, would provide 15' of dim light for a character with this trait, making them able to see BETTER than someone with unlimited low-light vision.
This is the only reference to low-light vision having a "range" that I can find. Was this intended to refer to Darkvision instead? If it's supposed to be Darkvision, then everything makes sense.
