Sorcerers are a bit more balanced in [[Hellfire]], at least in the Crypt levels, where monsters are found in wider varieties, and plenty of them are immune to both Fire and Lightning.
The Sorcerer was replaced by the Sorceress as a playable character in Diablo II, though the Iron Wolf [[mercenaries]] of Act Three were clearly modeled after Diablo I's Sorcerer. The game lore went on to say that the Sorcerer character from Diablo became [[the Summoner]], the boss monster found in the Arcane Sanctuary in Act Two.
