1. If you have a item that let's you teleport can you teleport to the final spot for one of the corner boards that you are in.Depends how the effect is worded. If it says "any space in the same region" as most teleportations do, you can go to the last space in the corner region from that region, but not from the outer region.
If the answer is yes can you teleport to the end square of a corner board from the outer region?
2. Can you get a path card if your not in the woodland region. If yes do you lose it when you change regions. Even if that region change is going into the woods.
Yes, yes, yes.
3 There is a woodland event that causes you to make your own deck of adventure cards. Do you always draw form that deck until it's gone or only when you are in the region where you got the card.You would have to provide the text of that specific card for me to answer that.
