In Merchants of Magick, which takes place in the "Set a Watch" universe, you are the owner of a magic item shoppe, crafting items and researching spells to sell to the Adventurers of the Watch.
Each round, four polyhedral dice are rolled, then you select two of them to craft items or research enchantments for your shoppe. As you craft items and research spells, you start stocking items and earn potions that let you manipulate the dice. Adventurers travel from shoppe to shoppe, so you need to stock the exact items on the order cards in front of you. If you have an item an Adventurer needs, you earn coin — but if you wait too long to fulfill an order, Adventurers will become impatient and visit your competitor next door!
After ten rounds, the player who has earned the most coin wins.
