Some friends and I were playing this game tonight, and came to a fairly vehement disagreement on the usage of the Elder Sign item. I argue that if you use the elder sign item, you do not need to first close the gate. All three of my friends argue that you do have to close the gate first. It seems so obvious to me from the way things are worded that you don't have to close the gate first, but I suppose I could be wrong. You might be able to predict my question.
After emerging from a gate and marking yourself as having explored the gate, can I then immediately use my elder sign (and pay the costs listed on the card) to seal the gate without first having to close it?

How do you calmly discuss anything with a guy that, when you make a perfectly valid point supported by the wording of the rule/card, insists it must be a misprint? I'd lose it. Clean snap. In the case of the Elder Sign, there is absolutely NO room for interpretation. Zero. Elder Signs have always been a part of the game, the game has been revised and has seen numerous rules updates and clarification. Fantasy Flight even went so far as to re-release certain cards like Flesh Ward and Healing Stone. Does your friend honestly think FFG would overlook a misprint on a card as vitally important as an Elder Sign?
