Right. But that's not what was asked. The sword is not part of the dragon. Roy's ability to PWOK! the Sword has zero relevance to which parts of the dragon are inside or outside of the AMF. Only whether the sword is inside our outside the AMF matters (well, and Roy, of course).
Roy is not trying to affect the dragon with his ability to retreive his sword. He's only affecting the sword.
Which is all great information about how an AMF works, but not the actual question which was asked, and to which you replied:
He's literally asking if, when someone is only partially within an AMF, that area is considered to be "extended" to cover the entirety of that someone (in this case a dragon), or not.Originally Posted by bunson_h
The answer is: Not.
Ergo, as long as the sword is outside of the AMF, Roy can PWOK! it, even if Calder is holding it, while most of the rest of him is inside the AMF. Bunsen clearly wasn't sure if, when a creature is partially inside an AMF, whether the effect of the AMF basically stretched around the entire creature (which might affect Roy's ability to retrieve his sword). It was a legitimate question to ask, since some game systems might just say something like "if any part of you is inside the effect, you are treated as if all of you is inside it", in which case an argument could be made that this includes any objects worn or held by you as well.
D&D rules on AMF do not allow the creature inside the AMF to be targetted by spells, but can be affected by AE spell effects on the parts of the creature that are outside the AMF (usually damage effects). Which gives us a strong clue as to the correct answer in this case.
