The Affliction Necromancer build is one of the most strategic and rewarding playstyles in Diablo 4 Season 12. Unlike burst-heavy builds that rely on massive single hits, this setup focuses on damage-over-time (DoT), curses, and shadow damage to slowly drain enemies while maintaining strong survivability.

If you're looking for a build that excels in boss fights, elite encounters, and sustained combat, this guide breaks down everything you need to know-from core skills to gear optimization using powerful Diablo 4 Items.
