The fires of war have begun to smolder, and it's clear that an end to the Reign of War is in sight. Echoes of Myth, the final planned expansion for Omen: A Reign of War, introduces twelve brand new units, including an all new unit type: Spirits. When a Spirit enters a City, it has two different abilities, and you choose which one you will use. However, you have the option of paying the Spirit's cost, plus a little extra, and discarding it from your hand to use both abilities.
