This is strictly correct, but the point still stands. The resulting Blood charm provides SIGHT, which includes conventional sight ("the character’s normal vision through the gem is slightly cloudy") and astral sight. It also consumes an eye, which is exceptionally symbolic, if nothing more.etherial wrote:Astral-Sensitive Eye does not alter the eye. IT CONSUMES THE EYE.
You are correct, there is no requirement. There is also no statement that eyes are not required. It's like saying that "a character lifts the door" doesn't require arms because it doesn't explicitly say it requires arms. What is the near 100% way that Namegivers lift things? With arms.etherial wrote:Having literal eyes has never been a requirement for Astral Sight because blind folks seeing oogy magical stuff is really common in fantasy (Rogue One: A Star Wars Story, for example).
Lastly, "seeing" and "sensing" are different things. Let's take the horrible, horrible movie that was Daredevil as an example. He could not see, he never claimed to be able to see, but he could sense AS THOUGH HE COULD SEE. You see the same thing with echo-location: blind people/things are able to create an impression of their environment, which includes distance, but it is not SIGHT, they have no concept of color and other things that require visual acuity. Sight is a specific thing, perception is not.
So, it's entirely possible that sight was not intended as sight in the sense of eyes. However, they could have chosen much better words in that case.
