• Hello, and welcome to the forum!

      Anytime you collect keys for your personal Adventurer's Challenge, the same amount of keys is credited towards the Guild's Challenge of the guild you are in (if any). If you change your guild during the current season, you no longer score keys for the guild you've left - instead, you start scoring these keys for the guild you've switched to. Any keys you've scored for the old guild remain in the old guild, you don't "transfer" them no matter how many times you change guilds.

      Hope that helps.
