Each character gains a mastery at level two and another at level eight. These masteries range from the standard sword and board of Warrior or Defense, to the spell casting variety of Dream or Storm. There are ten different classes, (nine in the base game, Titan Quest: Ragnarok adds the tenth), called “masteries,” for you to choose from.

Building up your character is the main point of this style of game. Of course, the story of Titan Quest is just a medium for giving you a reason to hack and to slash. With the mortal realm having their connection to the realm of the gods severed by a mysterious race of demons called the Telkines, it is up to you to trek across the continent and assist the surviving armies of Greece, Egypt, and China in fighting off the monster hordes. You play as either a male or female human who finds themselves in the midst of a monster apocalypse, with hordes of all kinds of mythical horrors pouring into the world of man. The premise of Titan Quest is about what you would expect for a Greek-themed Diablo 2.
