One Deck Dungeon: Relics of the Forge

From BoardGameGeek:

One Deck Dungeon returns with a brand new full expansion! The Forge hungers for fuel, and it will reward your efforts with great power if you satisfy it. During Setup, you'll choose a Relic to enter the dungeon with. This Relic will shape your strategies, as it will be your means for filling the Forge with fuel, and also a powerful way to expend it! This expansion is stand-alone, and contains all new dungeons, heroes, monsters, traps. -description from the publisher
