GameSpot has tossed up a preview of Titan Quest: Immortal Throne, after getting some hands-on time with Iron Lore's upcoming expansion pack.
One of the major new features of Immortal Throne is the new dream mastery. In Titan Quest, there are no distinct class types, such as warrior or thief, as there are in most role-playing games. Instead, there are nine masteries that you pick two of when creating a character. That way, by combining different masteries together, you can create all sorts of interesting character combinations. For example, you can create a magic-wielding fighter if you combine the warfare mastery with the storm, nature, or spirit masteries. The new dream mastery focuses on tapping into the power of the dream realm. For instance, the temporal flux ability lets you accelerate time around your character, letting your character attack more quickly while causing enemies to move more slowly. The trance of convalescence results in increased life recovery and damage absorption for your character and allies. And the distortion wave causes ripples in the fabric of reality, damaging enemies considerably. The new dream mastery is also available if you create a new character in the original game (assuming you have the expansion installed), so you can play with these new abilities from the very beginning if you'd like.
