―Ezio getting the Climb Leap Glove from Leonardo da Vinci.[src]
A further upgrade to the Cestus called the Climb Leap Glove could be bought from Leonardo da Vinci upon Ezio's arrival in Rome.
Aside from granting the same advantages to damage and speed, it also returned the Climb Leap ability previously taught to Ezio by Rosa, which he became unable to perform unassisted after being injured during the Siege of Monteriggioni.
By the time he journeyed to Constantinople looking for Altaïr's hidden library, Ezio no longer needed the Metal Cestus and could climb leap freely. The hookblade replaced both his Metal Cestus and his secondary Hidden Blade, yet he could still climb leap when near the top of the building.
