Diablo Heroes

Diablo character classes
The original Diablo has three heroes to choose from: Warrior, Rogue, and Sorcerer. Diablo 2 introduced: Amazon, Necromancer, Barbarian, Sorceress, and Paladin. LoD added Druid and Assassin.

Warrior

The warrior is a powerful melee fighter, master of weapons of war and capable of enduring more damage than any of the other classes. Seeking fortune and glory, warriors come to Tristram every day to challenge the dark unknown in the subterranean labyrinth. They are not necessarily of any particular clan or group and range from barbarians from the northern highlands to noble paladins. Warriors are able to repair their equipment at the cost of diminishing maximum durability. The amount of maximum durability lost with use decreases as character level increases. Given this lost durability, most players opt instead to pay for non-destructive repairs in town for equipment they will be using in the long-term.

Rogue

The Sisters of the Sightless Eye are the best archers in the world of Sanctuary and the rogue therefore is master of killing enemies from a distance. They can have a higher level of magic than warriors and thus are able to make better use of magic in their battles, although not nearly as well as sorcerers. Willing to test their skills against the evil in the labyrinth, where untold riches are rumored to be stashed, rogues have come from the far east to Tristram. Rogues have the ability to spot doors, chests and sarcophagi that have traps and are able to disarm them. The chance to successfully disarm a trap increases with the character's dexterity attribute.

Sorcerer

A powerful master of the arcane arts, the sorcerer is the hero that is able to achieve the greatest heights of magic, so that he never really has need of physical weapons - he can kill his enemies solely with magic, whether it would be balls and walls of fire or powerful bolts of lightning. Eager to gather knowledge about demons and see them slain, sorcerer acolytes of the Vizjerei mage clan have come to Tristram - seeking to discover long lost tomes of magic knowledge under the cathedral. The sorcerer is able to recharge magic staves at the cost of the maximum number of charges. The amount of maximum charges lost with use decreases as character level increases. As per the warrior class's skill, this is less-used in late-game and with equipment used in the long-term

Diablo Character differences
The Warrior has an innately higher chance to hit in melee combat, a chance to cause a critical hit (causing twice the original damage; other characters lack this), as well as the best chance to block with a shield. Also there are fewer frames per swing with melee weapons. The Rogue calculates not only her strength but her dexterity as well when determining the damage she can deal with a bow and also has a faster rate of fire similar to the warrior with melee weapons. The Sorcerer has the highest chance to hit with a magical spell and faster cast rate, as well as gaining more mana than any other class from items that improve Magic.
