Swift Assassination is a recurring Helix Rift Event in Assassin's Creed: Rebellion that originally lasted from September 28–October 1, 2018. It comprised of six missions in which members of the Spanish Brotherhood who were adept in use of the Hidden Blade infiltrated Templar strongholds in Spain and eliminated members of the Spanish Rite. Successful mission synchronization gave players Data Nodes which unlocked various reward tiers based on the total Nodes collected, with the top tier granting players the character Ezio Auditore da Firenze to play in future missions; a pair of Hidden Blades, set of medium armor, and accessories scaled to one's Brotherhood level; and coins. Players could earn extra Nodes if they used one or more of the following Sync Bonus Heroes:
|Hero||Bonus Data Nodes|
|Mateo Galan||+25% initially, +25% for each additional rank|
|Magdalena Suárez||+50% initially, +25% for each additional rank|
