[QUOTE="FrogReaver, post: 7547288, member: 6795602"] The spell let's you create an image of a wall and allows an action with an investigation check to disbelieve the illusion. My take is that this means the illusion appears to be real in every way imaginable unless you can pass your investigation check. That check is what determines if something is unusual about the illusion which can be narrated as any number of phenomenon or inconsistencies with the illusion. So if you ask me as the DM a bunch of questions trying to figure out if it's an illusion before making an investigation check then every one of those questions will be answered in whatever way would be consistent with that object actually being there. After you pass your investigation check I will come up with some other phenomenon to describe as finally indicating to you that this particular object was an illusion. To Alice, she would be in the dark, to Bob who knows it's an illusion he would see Alice in the light. So if you ask Alice or anyone that doesn't know it's an illusion if light passes through the answer is no. If you ask Bob or anyone that does the answer is yes. If Alice hasn't yet passed her investigation check then everything would indicate to alice that there was a wall actually present there. Presumably Bob knows it's an illusion and everything will appear to him as if there is no wall there. no. Kind of. As long as you believe it's an illusion then it will behave exactly like a mirror. Personally I assume the caster knows his spell is an illusion and thus he could never get such a benefit from such an illusionary mirror, however other players in the party could (at least till someone tried to grab said mirror). Whether the illusion actually reflects light or emits it's own isn't important unless there is a way for a player to observe the difference. I know of no way so I can't say which the illusionary mirror that's believed to be an illusion actually does. However, if there was a way to know if the illusionary mirror reflected or emited it's own light then it would behave exactly as the a real mirror until it's known to be an illusion. Presumably the illusionist could decide and the magic can take care of the details. The rules only provide 2 ways to determine something is an illusion. Simply believing it's not because someone told you is apparently not adequate for you to cease to be effected by the illusion. You must either see something pass through it or pass an investigation check regarding it. [/QUOTE]
