Once a player is killed by a monster, there is a chance of a red void portal appearing near the character's body, indicating that the Nemesis has been created (Elite monsters seems to have higher chances to create a Nemesis). They do not appear for Hardcore characters. The Nemesis will spawn in your world based on your profile, ignoring your character level while keeping what ever levels it has gained. They can also spawn in co-op games for players in the same instance.

Among these rewards are Player Gifts and possible chances of rare or legendary items. By killing these monsters, players can 'avenge' their friend's death and earn special rewards. Through this system, monsters who have killed a player can appear in the game of players on the original player's Friends List, identified clearly as 'Nemesis, Killer of: (character name)' and becoming even more powerful than they were in the original player's game. Nemesis Kills are a feature of Diablo III: Ultimate Evil Edition (exclusive to consoles as of patch 2.4).
