Hey board game enthusiasts! If you're into the exploration and resource management of 'Lost Ruins of Arnak,' get ready for a little something extra to spice up your adventures. This is the Rat Promo Card, a promotional card that first popped up at Spiel Essen 2024 and later showed up on the CGE website. It doesn't fundamentally change the game, but it adds a neat tactical twist that can make a difference.

The main action of this card is simple yet clever: it allows you to return one of your workers, already placed at a campsite, back to your personal player board. Think about it: sometimes you place a worker somewhere and later realize you need them more in another spot, or you simply want to free them up for a new round of actions. This card gives you that flexibility! It's like having a 'recall' button for one of your exploration agents.

For those who already master the islands of Arnak, this little card is a nice treat. It won't overload your brain with complex new rules, but it offers an additional tool to optimize your plays. It's the kind of thing a more experienced player will know how to leverage to gain that subtle advantage. If you're an Arnak fan and enjoy optimizing every move, this promo card is a cool little addition to your collection. It doesn't reinvent the wheel, but it adds an extra layer of fun and strategy for those who already love the base game.
