Sand Castle Games Res Arcana - Lux et Tenebrae Expansion
In a dark cathedral, a mage harnesses the power of demons to fuel her spells. In an alchemical laboratory, a diviner inscribes a scroll of destruction. Meanwhile, a bard and a beastmaster seek out the prismatic dragon and the golden lion to hold the forces of darkness at bay.
Lux et Tenebrae — light and darkness — is the first Res Arcana expansion. It expands the game to 5 players, introduces a new artifact type in Demons, and adds Scrolls: special one-use powers that can be gained in one round and saved for a future round.
New mages, magic items, monuments, and places of power further deepen the game's replayability and open up new strategic pathways to victory. The expansion also fits perfectly into the base game box, so it won't take up any extra space on your shelf.
