So I need to know how to have an event happen only once;
i.e., you talk to a man sitting in a tavern; the message is:
"I have something for you", and a 2nd event is that he gives you a Talisman.
How do I make it so that when you talk to him again, he does not add another Talisman to your inventory?
And better yet, how can I make him (or any other event with a message, for that matter) say something different the 2nd time you talk to him?
