Baal

Baal (pronounced bay-el in North America, and bah-l in Europe) is the Lord of Destruction, the middle brother of the three Prime Evils.

Before the encounter, Baal summons monsters from each Act. Once all 5 groups of monsters are slain, Baal will go into the Worldstone Chamber. Baal is the final boss in Diablo II: Lord of Destruction and possesses a variety of deadly special attacks. He has moves such as: The duplicate is not as strong as Baal and does not drop any items.
 * Hoarfrost - sends a chilling wave that chills and knocks back the player at the same time, dealing damage multiple times if the player is knocked back a decent ways.
 * Fire Nova - similar to Diablo's, a ring of torches (like those the Act V Imps cast) is sent out in all directions.
 * Mana Rift - a fire breath move which drains mana (seen in cinematic), at a rate that is comparable to a monster with Mana Burn.
 * Destructive Strike
 * Teleport
 * Summon Clone - summons a duplicate of himself, which can cast all of the real Baal's moves as well, except creating a second clone (only one Baal clone can be up at a time)
 * Festering Appendages - summons tentacles that come out of the ground to attack the player
