The Art of the Heist is a recurring Helix Rift Event in Assassin's Creed: Rebellion that originally lasted from August 29–September 3, 2018. It comprises of five missions set during the Reconquista in which the Spanish Brotherhood of Assassins were aided by the Spanish Thieves' Guild in retrieving Leonardo da Vinci's paintings The Celestial Mysteries from Inquisition forces throughout Spain.
Successful mission synchronization gives players Data Nodes which unlock various reward tiers based on the total Nodes collected, with the top tier granting players the ability to play Lupo Gallego in future missions; a long weapon, set of medium armor, and accessories scaled to one's Brotherhood level; and Codex. Players can earn extra Nodes if they used one or more preset Sync Bonus Heroes.
