Video games - Diablo II: Lord of Destruction

• A fifth act taking place in and around Mount Arreat in the northern Barbarian Highlands, with an additional act boss, Baal.
• Ethereal items: These transparent items cannot be repaired, but they may also have better characteristics than their repairable equivalents.
• Jewels: items serving a similar purpose to gems in that they can be placed in socketed items, but which have random characteristics as opposed to the set characteristics of gems and runes.
• Charms: items giving boosts to character's stats when kept in the inventory of the player.
• Two new character classes: the Assassin and the Druid.
• An expanded private stash (double the Diablo II
  stash).
• An alternate weapon/shield setup that can be switched between via a hotkey in gameplay.
• Runes: stones that give powerful attributes to a socketed item when placed in it, or even more powerful bonuses when placed in a certain order forming a "runeword" (see section below for more information).
• Hirelings (mercenaries) can now follow the player outside of the Act in which they were hired. They can also be equipped with armor, a helm, and a hireling-specific weapon (as well as a shield in some cases). Hirelings also gain experience and can be resurrected (for a price equivalent to their level) when killed.
• Class-specific items: new items that only a specific character class can use. These items often contain class-specific bonuses, often adding additional skill points for that character class.
• Elite items: more powerful versions of items following the Normal and Exceptional items.
• New unique items, including many Exceptional and Elite Uniques.
• New set items, including sets that use Class-specific items (ie. only one character class can complete certain sets).
• The game can now be played at 800x600 resolution, up from the standard 640x480.
