A mana bomb is a mana cystal that has been charged to the point where it has become unstable. Upon contact with a mana shield, it releases a tremendous explosion. During the Black Sun Siege, the Black Sun attackers used mana bombs to blow a considerably sized hole in Ther'avare's eastern wall, injuring many of the defenders in the process. Later in a last desperate attempt to turn the tide of the battle, Kir'ima grabbed an unused mana bomb that was lying around and attempted to suicide bomb the leader of the attackers. The attempt failed in killing the Black Sun leader, although it did create a lull in the battle and gave the Tei'kaliath survivors the opportunity they needed to escape from Ther'avare.
