Once-Per-Game Abilities
De omschrijving van deze Mechanic op boardgamegeek.com is:
Players have a special ability that they can use one time per game. These may be unique to them, like 'feats' in Warmachine, or common to all players, like the special power chits in Finca. Often players will receive bonus Victory Points if they do not use their one-time abilities during the game.
