When bidding for artifacts during age changes, can a player bid for more than one artifact if they have enough bid token points for that category? F.E. can a player possess the Sword of Atlantis and The Cobra Crown simultaneously?
No. You bid with only one type of adventure token, and can win (at most) only one artifact. However, it is possible for the last place player (who always gets the "Conan Bid Bonus" card) to win an artifact.
