Worldstone Chamber

The

Worldstone Chamber is the final level of Act 5 (excluding the

Pandemonium Event levels) in which you face the game's final boss,

Baal.

Tyrael reports to you that it is too late after defeating

Baal, and the room begins to shake as the Worldstone begins to disintegrate. After proceeding through the dialogue, you are then presented with the final cinematic of the game and begin a new game in the next difficulty.
