Characteristic tasks of Assassin's Creed Brotherhood:

Union challenge:

After rebuilding the headquarters of socialites, thieves and mercenaries, unlock the corresponding trade union challenges, and after recruiting the first novice assassin, unlock the assassin trade union challenges. Among them, the challenge of the Assassin's League is the simplest and can generally be completed during the main task. The reward is to unlock the strongest main weapon, the sword of Artur and the assassin's coat of arms.

After the challenge is completed, the social butterfly union rewards Maria's dagger (the second-generation Sudanese dagger) and the social butterfly union's shield, the mercenary rewards bartholomew's axe and the mercenary's shield, and the thief rewards Lapop's sword and the thief's shield. Not very useful, but spiritual.
