Ok, thank you for your advices. Can you tell me how to enter a new world? Which one is that? I am on "York Castle". Also if I enter a tribe do I have a guarantee they would rush to help out a new member? THanks.
Edit: Although I appreciate your advice as well as Jhin's Guide, as a relatively new player I found it rather....confusing, so to say. Simply because I do not know the game's "vocabulary", and the guide does not explain some terms. So I have no idea what are "cats", "trains", "sniping", "nukes", etc....
