I grew up in a forest. I know exactly what they're like. If you'd like to get into a debate on the detailed specifics of shadows, I can do that. Technically, all a shadow is is a place that has less light than the places around it, which would essentially give your character an awareness of the entire universe except the portion surrounding the brightest star. A shadow isn't an actual thing, it's just what we call a place where there is noticeably less light than the places around it. Taken to its logical conclusion, his ability to see shadows gives him something very near to omniscience, which would be a blatantly overpowered ability. 

My point here is that you can pretty much say he can see anything anywhere and get away with it due to the ambiguity of the power itself, and the fact that a logical progression cannot be applied to the power without making the situation even worse. As the thread creator, this is ultimately your playground, but as the other guy who reviews the abilities, I've had a bad feeling about most of the stuff your character can do from the beginning. I didn't bring most of it up then because I wanted to give you the benefit of the doubt, but you've demonstrated twice now that you have no problem ignoring the constraints placed on your character and his abilities (the first time when you dematerialized two posts in a row, and this time when you dematerialized to grab the weapons then did it again to return). The fact that you changed it after getting called on it is irrelevant, since it clearly wasn't just a bout of forgetfulness. Not after happening twice. 

I understand that it saps the fun out of fights when debates like this keep happening, but the rules and limitations laid out for the character were very clear. To quote your amended CS: "turning into a shadow is used to avoid otherwise fatal attacks, avoid attention or maneuver for an attack. both have a one turn cooldown after use and only last for the turn they are used in." That is the ability that was approved, and nowhere does it say anything about partial transformation, or reaching out with a partially transformed limb to retrieve something. Twice now you've very clearly broken the rules, and yet you seem to think that it's my fault these debates keep happening.
