Got the dunwich horror expansion a few weeks ago. Just played a game where we had the gate box item/call friend spell combo, which was very nice. I have a couple of questions about it the mechanics.

1. The spell mentions that the friend getting called cannot have already moved: " Cast and exhaust to choose an investigator in Arkham who has not moved this turn." Does this mean that it cannot be used on a investigator who has gone through his movement phase but didnt move to a different spot (so essentially if you are the last player you cant cast the spell), or does it mean you can cast it to move anyone who hasn't "moved"?

2. When you are in another world can you cast it when you move to from the first to second spot and therefore the "friend" that you move winds up in the second position of the other world or would he have to go to the first position of the other world?

1. "Moved" here is to be intended as "has not resolved his movement phase yet"

2. Nope, since the spell allows you to target an investigator in Arkham (Other Worlds are not considered part of Arkham)

Hope this helps!
