Ascension Darkness Unleashed
Ascension: Darkness Unleashed is both a standalone game for two players and an expansion that can be combined with Ascension: Rise of Vigil or other Ascension games.
Ascension: Darkness Unleashed features "Dark Energy Shards", a new take on the "Energy Shard" Treasure cards introduced in Ascension: Rise of Vigil. Like an "Energy Shard", a "Dark Energy Shard" allows a player to draw a new card while providing one energy to power up Energize cards. In addition, the Fate effect allows each player to banish a card in his discard pile whenever a "Dark Energy Shard" is placed in the center row.
