One Lure for challenge cards, two Lucre for non-challenge cards. They are then discarded. Play at the end of your turn. If the infector accepts, he must take the full loss and discard this card. The first player is immune until all have had it, and no one may catch it more than once a turn.
All players challenge each other on one planet that they share a base.
In case of a tie, all players involved lose. Play between challenges. Players use their own powers first in conflicts. One player's tokens do not count towards the total in a challenge. They still gain rewards.
