Location and loot

The rule of thumb for finding a Nemesis is that he will be in “his element”, for example don't expect to find the Nemesis of the Aether faction in Blood Groove or in Act 7!

If your goal is to hunt one in particular, I recommend this guide to all possible locations of nemesis, it will take you a little while but you will be sure not to miss it!

Each Nemesis can give you an epaulet (base game), pants (AoM) with +3 on two spells (see list below). FG's Nemesis will give you an amulet. There will also be an item cache at the spawn location, be sure to grab it!
