From Introduction: This is a Booster Pack for the ADASTRA setting. Booster Packs are self contained and holds only the information needed to play the item contained within. In this case it is feats. Many feats and abilities grant a character counters. Counters stay with a character until an event dismisses the counters. Counters of the same name stack with each other no matter what the source is. DMs have the ability to dismiss counters at will.
