Sorceress Skills

From Diablo 2 Wiki
Sorceress Skills

The Sorceress' spells are divided into skill trees sorted by elemental type. Each tree can be used to devastating effect, with the right equipment and tactics.

In the early versions of Diablo II, most Sorceresses spread their skill points across all three trees, using a variety of skills. In v1.11, thanks to more powerful monsters and synergies making linked clusters of skills so much more effective, most Sorceresses are specialized into one or at most two skill trees. This makes them more powerful with one element, but less able to deal with all types of monsters.
