Rune words: Rune words are spells that are created by inserting specific runes into sockets on weapons and armor. Each rune word provides a unique combination of bonuses and abilities that can enhance a player's character.

Socketing items: In order to create rune words, players must first find items with sockets. These items can be randomly generated by monsters or obtained by completing specific quests.

Trading: Like in the original game, trading runes and rune words with other players is a big part of Diablo II: Resurrected's community. As players progress through the game, they may find themselves in possession of rare and powerful runes that other players are willing to trade for.

Endgame content: Once players have obtained powerful runes, they can use them to create endgame gear that can help them tackle the game's toughest challenges. Players can create runewords that provide massive stat boosts or grant special abilities like teleportation or mana regeneration.
