Nemesis spawns have a chance to appear in just about any area where their Faction is present. Nemesis spawns are ultra-rare bosses, champions of their respective Faction that represent some of the toughest encounters you will face in Grim Dawn.
As you slay your foes, you will gradually unlock additional monster spawns, increased Hero spawns and, upon reaching Nemesis status, Nemesis spawns. Just as improving your reputation with friendly Factions can earn you rewards, angering hostile Factions has ramifications as well. Mandates significantly increase all reputation gains but, unlike Writs, can be placed in your Shared Stash to use on all your characters. As a testament to your dedication, reaching Revered status allows you to purchase a Faction’s Mandate.
