Two Worlds will also have a deep role-playing system that is based primarily on open-ended character skills. You will need to choose a starting character class but will then be free to advance your character in any line of skills. These skills include picking locks, using various weapons, or casting magic spells from one of five schools of magic, which include elemental sorceries and the dark arts of necromancy. Interestingly, necromancy--the magic of raising the dead and manipulating their undead spirits--won't exist in the world at first; you'll need to undertake a quest to restore it to the world by reactivating a set of ancient towers. If you choose not to restore necromancy, then it simply won't exist throughout the entire game, and you'll never have to swing your sword at a single skeleton or zombie. Fortunately, the game will also feature "skill trainer" characters who can help you learn new skills and unlearn those you've chosen but don't like.
