I am debateing on getting a shard transfer shield but I have a question or two about them and need to know answers before I get one. First: If i get a shield lets say on Atlantic and select it for Catskills.. this means the shield that I get on Atlantic will take me to Catskills, I know that one. Now what I am not sure of.. is it says it's used once a month. Does this mean it needs to be locked down in house all the time for use? And/or does the shield come with me or just a token come out of the locked down shield? And finally... once Catskills is selected.. that is the ONLY token that you will get once a month out of the locked down shield? Hope this makes sence.
