The Elite Attack Die is a participation prize given to players who participated in Month 1, "Operation Return," of the Star Trek: Attack Wing Storyline Organized Play Event, The Dominion War. It is considered a Resource.
Resource:
Beginning with Month 2 of the Dominion War Organized Play Event, "The Battle of Chin'toka," each player may equip their fleet with exactly 1 Resource. The Squadron Point Costs for Resources are located on the Resource Reference Cards. Players may choose from among any available Resources for the Dominion War Storyline OP, but cannot change Resources between Battle Rounds.
Once each round, the Elite Attack Die may be exchanged for 1 of its player's normal attack dice. Each face of the Elite Attack Die has a result on it, as opposed to the blanks on normal attack dice, and thus gives a greater chance of a positive outcome for the attacking player. The Elite Attack Die may be added to a squadron for 5 Squadron Points.
