The Mandalorian and Grogu are ready to join the battles of Star Wars: Legion with this Operative Expansion! Din Djarin, also known as the Mandalorian, expands the game’s mercenary forces with his skills as a bounty hunter. Joining him as a counterpart is Grogu, a foundling with a strong connection to the Force. Together, they form a potent duo that can also enhance your players’ Rebel and Imperial armies. In addition to their latent abilities provided on two unit cards, this expansion also includes four command cards that give them even more strategic options in battle. Finally, four upgrade cards give players the freedom to outfit Djarin with an array of additional equipment, including his Amban Rifle or a Baskar Spear.
