Free to Download: Deck of Fates from Black Forge

Black Forge is the publishing company of the Portland-based illustrator J Smith.

A free to download Deck of Fates is a set of cards for players to find in-game.

The Deck of Fates is a powerful set of cards crafted by the old gods for use in rituals long forgotten. Drawing a card carries the weight of a powerful reward or debilitating consequence from an action you have yet to take. The deck is never found on its own, but instead is always in the custody of a mysterious keeper who is eager to let others draw from it.

The PDF product comes in two parts; a quick preview and a full preview. One emphasises the art, and the other has a description of the flavour and mechanical effects for 5e games.

DriveThruRPG can sell the cards as a physical product, but the PDFs make excellent previews.

A traveling fortune teller presents the Deck of Fates. The deck will tell your fortune, but the fortune teller warns that part of your fate will reach back and touch you in the here and now.
After you save him from a group of bandits, a priest dressed in the trappings of a long dead god and the glint of madness in his eyes insists you draw from the deck as a reward.
A merchant of rare tomes and scrolls displays the deck proudly behind the counter. When asked about it, she offers to let you draw a card from it but advises caution. The deck gives off a powerful magic aura, but attempts to identify it magically or otherwise have failed.
