Also, when Ezio receives his Assassin's mark, a glitch may occur, because Altaïr had his ring finger removed. If wearing the robes of Altaïr when acquiring the Hidden Blade, instead of wearing Altaïr's robes, you will wear Ezio's, but after Leonardo gives him the blade, the robes will change into Altaïr's. Unlike in the first Assassin's Creed game, there is no scabbard for Altaïr's sword it simply hangs at his hip with the blade exposed. The player can still use the dual Hidden Blades, but there is no blade visible on Altaïr's right hand. The scabbard for the knife on his back is also empty, and the animation for putting the knife away shows it being placed on the hip, by the sword, but it disappears once put away. If Ezio has no more throwing knives, the holders are still full of them.

There are several glitches while wearing Altaïr's Robes.

Additionally, though Ezio's voice remains the same, he does not speak during taunts, instead only gesturing towards the opponent, similarly to Desmond's taunting motions in the credits scene. The differences of the models are that the left ring finger is amputated, the right Hidden Blade does not have physical form on the character (despite being usable), and the beard that Ezio gains during the Battle of Forlì sequence is not present, during or after these sequences.

Altaïr's Robes change Ezio's model to Altaïr's, the same seen in Desmond's hallucination sequence.
