Metal Cestus

The Metal Cestus is an upgrade to Ezio Auditore's fists weapon slot. It can be purchased from any blacksmith for 2000f in Assassin's Creed II and by Leonardo da Vinci for 6100f in Assassin's Creed: Brotherhood. When equipped, it will boost the damage of fists from 1 to 3. It will be automatically equipped when purchased, and cannot be unequipped.

Assassin's Creed II
The Metal Cestus upgrade will give you a slight advantage for Beat Up events, and any other instances that involve unarmed fighting. A particularly useful moment to have the Metal Cestus equipped is during the last fight against Rodrigo Borgia, wherein you are disarmed of all weapons except the Metal Cestus/Fists. The origin of this weapon is the ancient Roman Empire, where gladiators used weapons similar to the Cestus in arena fights.

Assassin's Creed: Brotherhood


"Now nothing will be out of my reach."

- Ezio Auditore, getting the Climb Leap Glove from Leonardo da Vinci

In Brotherhood, the Metal Cestus is known as the Climb Leap Glove, and grants Ezio the same damage and speed boosts gained from the gloved weapon in Assassin's Creed II. In addition, it returns the Climb Leap ability previously taught to Ezio by Rosa, a move that he was unable to perform unassisted after being injured in the Siege of Monteriggioni.

The Metal Cestus is the only small weapon you can have equipped along with another small weapon, though they cannot be used together.

Trivia

 * At the beginning of Brotherhood when Ezio is wearing the Armor of Altaïr, the Metal Cestus is not present.
 * Purchasing the Climb Leap Glove before the secondary hidden blade will affix the metal plating directly onto Ezio's fingers. A similar effect can be achieved by replaying any sequence where the Armor of Brutus is worn, then re-equipping another set of armor.
 * In the Assassin's Creed: Brotherhood novel, it is said that the glove that Leonardo sells to Ezio would improve his climbing abilities to that of a gecko.
