Yes, but you need to choose heroes whose class matches the weapons. Besides, six weapons cannot be obtained in the game. Two of them (the Staff of the Eight Aspects of Ashih and the Blade of Chaos) can be obtained for an "exclusive" reward, and the Sar-Aggretta Staff, the Staff of Purification, the Perfect Silk Sword, and the Flaming Dragon Tongue can only be obtained through an exploit, which can be found in the "Dynasty Weapons" topic.
