The Mask of the Ibis

The Mask of the Ibis is a Helix Rift Event in Assassin's Creed: Rebellion. It comprised of five missions set in Egypt shortly after the founding of the Hidden Ones, in which Bayek of Siwa and Kensa hunted down the Ibis Reborn, a cult leader who had retrieved the titular mask that once belonged to The Ibis and sought to revive the Egyptian chapter of the Order of the Ancients, believing themselves to be the reincarnation of the late priest. 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 name to play in future missions; a weapon, set of armor, and accessories scaled to one's Brotherhood level; and coins/codex. Players could earn extra Nodes if they used one or more of the following Sync Bonus Heroes:
