Assassins Guild

 * 25 Apprentices signaled during a fight.
 * 15 Arrow Storms.
 * 20 Assassin Recruits signaled to kill a target.
 * 5 Assassin Recruits signaled within a core memory.
 * 5 Recruits raised to the rank of Assassino.

Upon completing all five of these challenges, the player unlocks the Assassin's Guild crest, as well as Altaïr's Sword at Ezio's hideout

Mercenaries Guild

 * 10 Mercenary groups sent to attack guards.
 * 5 Scaffolds destroyed by thrown guards.
 * 25 Brutes killed.
 * 25 Papal guards killed

 * 10 Double Assassinations.
 * 5 Guards disarmed and killed with their own weapons.
 * Kill 5 guards in 10 seconds.
 * 10 Streaks of at least 5 kills.

* "On horseback" means that the guards themselves must be on horseback, not Ezio. Also, some guards will start on foot, but jump onto a horse if you are fighting them. These will not count. The guard must have spawned on the horse.

Upon completing all ten of these challenges the player unlock Bartolomeo's Axe at Ezio's hideout.

Courtesans Guild

 * 10 Courtesan groups sent to distract guards.
 * 10 Enemies evaded using the crowd and other hide spots.

 * 10 Horses belonging to guards commandeered without killing the rider.
 * 5 Dead bodies hidden in wells or haystacks.
 * 15 Guards poisoned.
 * 20 Guards killed during a smoke bomb attack.
 * 10 Guards assassinated from behind.
 * 5 Guards assassinated from blind spots.

Upon completing all nine of these challenges the player unlock Maria's Dagger at Ezio's hideout.

Thieves Guild

 * 10 Thief groups sent to lure guards.
 * 1 Sprint uninterrupted for 300 meters.
 * 20 Jump from a horse to a beam.
 * 40 Leaps of faith.
 * 1 Perform a dive from a height of 25 meters.
 * 250 f pickpocketed.*
 * Glide a cumulative total of 500 meters with the parachute.
 * 25 Guards killed with a ranged weapon.
 * 5 Guards air assassinated from a beam.

* A glitch may occur if a player pickpockets too many people at the same time, which will cause the player to have unknowingly exceeded the amount. To avoid this, do not pickpocket people too quickly. This method has yet to be proven reliable.

Upon completing all nine of these challenges the player unlock La Volpe's Bite at Ezio's hideout.

Tips

 * The challenges do not account for any progress done before renovating the Guilds (and "unlocking" the Assassins Guild), so do not start on them until later in Sequence 3 (after renovating the Courtesan, Mercenary and Thieves' Guilds), and midway through Sequence 4 (the Assassins Guild).
 * To simplify the hiring challenge, you can keep renovating the faction building, making a corresponding group appear near (thieves appear on top) the faction building. Choose a random guard to distract/lure/attack, head back, renovate, repeat.

Assassins

 * A tactic to increase the speed of the Arrow Storm recharge meter is to send 6 Assassin Apprentices out on missions with similar time limits, then use Arrow Storm right before they're due to come back. When all 6 return near-simultaneously, the meter will recharge fully.
 * if you want to recruit assasins fast just send a 1 level assasin on a 4 or 5 stars contract with an assasino than the recruit wil gain several levels at once

Mercenaries

 * Since assassination from the ground doesn't count towards your progress for the Mercenary challenges specifying "on horseback," a good tactic is to either assassinate your targets from a horse (thus stealing their horse) or to kill them with a crossbow.
 * For the "kill 25 Papal Guards" challenge, one should look for the group of four Papal Guards that spawn at the entrance to the Vaticano district, or within the district itself, as Papal Guards are found nowhere else in the game outside of story missions.

Courtesans

 * For any who missed the "kill 20 enemies stationed at Guard Posts" challenge, the Memory "French Kiss" of the Baron de Valois Sequence is the most useful, as there are multiple guard posts targeted. Additionally, loading the mission but not starting it (by avoiding the exclamation mark) allows you to use the respawn trick.

Thieves
thumb|300px|right|How to easily complete 40 leaps of faith challenge.
 * Using the Antico district area near the Thieves Guild building is a good strategy for the challenge "sprint uninterrupted for 300 meters." You may also find an empty field and run around in a circle until you reach 300 meters.
 * Getting every Viewpoint will take you more than halfway to the goal of "40 leaps of faith," and using Leaps as an evasive maneuver in-game should get you the rest of the way.
 * The "pickpocket 250 f" challenge can be completed in a single pickpocket, by bribing a Herald with 500 f, and immediately stealing your money back.
 * A good place to get "20 jumps from a horse to a beam" is near Ezio's Hideout. There is a bridge next to the hideout, which has a beam stretching between two walls. Because of the open space, it's easier and less stressful. For it to count to the 20 jumps, you must spin around the beam once completely, making you sit on top of the beam. After spinning around the beam, you may also jump forward immediately to land back on your horse and save time.
 * if you have problems with the dive challenge go to the waypoint above ezio's hide out and make a jump don't forget to press a on xbox and x on ps3
