Knowledge Is Power

Knowledge is Power is a memory in Assassin's Creed II.

Description
During Venice's famed Carnevale, Ezio Auditore visited his friend Leonardo da Vinci, in order to ask him for a spare mask he could use to hide his idenity during the event. He also gave Leonardo more Codex pages for him to decode, which were later revealed to be the designs for a Pistol upgrade for the hidden blade. After Leonardo constructed the device, he set up three dummies for Ezio to practice on. After testing his new weapon, Ezio thanked Leonardo, put on the Carnevale mask, and headed onto the streets.

Outcome
Ezio receives and uses the pistol for the first time. Ezio is given a mask to keep him incognito.
