Introducing a new feature, "Crystals"!Having gone through the Crystal trilogy of Opus XII, Opus XIII, and Opus XIV, FFTCG now gains a new power. A portion of the Character abilities, and Summons will now appear with a new cost to be paid called "Crystals", not the usual "Crystal Points (CP)." Use abilities and more to gain "Crystals," and experience the latest strategy. Dice or counters can be used to keep track of the number of Crystals, but Crystal Dominion includes two kinds of premium version Crystal cards that can be used during games. Legacy cards appear once again in this set, with particularly popular cards from past sets included as premium full art cards.
