Dagger of Brutus
The Dagger of Brutus is a legendary dagger that is available in Assassin's Creed: Brotherhood, obtained along with the Armor of Brutus. It is said to be the same dagger that Marcus Junius Brutus used to kill Gaius Julius Caesar.
Having this special weapon equipped will strike fear into the hearts of civilians, and will make guards flee faster from fights due to its unique and brutal kill animations. It is the best short blade weapon in the game, with complete 5-star stats. The animations change, from the bone breaking moves to more viscious stabs (for example in one move Ezio stabs the guard on the chest then again in the back and tossess the corpse aside), similar to some of the multiplayer unique kills. Is unlocked by collecting all the Keys of Romulus and unlocking their secret armor
