The Meteorb Sorceress is a Sorceress build that focuses on the Meteor and Frozen Orb spells. Its name is a portmanteau on "Meteor" and "Orb."
The Meteorb Sorceress has the advantage of relying on two skill trees: Fire Spells and Cold Spells. Unlike some other Sorceress builds that focus on only one element, making them vulnerable in Hell mode due to increased monster immunities, the Meteorb Sorceress can often survive without help of teammates.
However, the Meteorb Sorceress often takes technique to utilize correctly. Meteor has a delay before hitting, and Frozen Orb can miss enemies completely if not aimed properly. Neither are very effective "panic buttons," and may not be useful in the hands of an inexperienced player. Still, with enough practice, the Meteorb sorceress can be one of the most powerful caster builds. To shore up their weakness of relying on time-delayed skills, Meteorb sorceresses can rely on Fireball as a backup. Since Fireball and Meteor have near-identical synergies, they can become very powerful on Meteorb sorceresses.
Meteorb builds have precious few superfluous skill points to spend: maximizing Meteor's power requires investing in Fire Bolt, Fireball, Meteor, and Fire Mastery--a total of eighty points, not counting other prerequisites. Frozen Orb and its prerequisites require an additional twenty five points. While some sorceress builds have the luxury of investing many points into utility skills such as Warmth or Energy Shield, every point spent this way on a Meteorb sorceress reduces her damage potential.
Meteorb Sorceresses are slightly harder to equip than others. Since they specialize in two separate skill trees, finding equipment that gives + to all skills is probably most prudent; however, depending on personal tastes, one could favor either Frozen Orb or Meteor over the other.
