Whether you're leveling up a new character or perfecting an endgame loadout, these nine overpowered builds are fan favorites for a reason. They make the most of class talent trees, synergistic gear, Diablo 4 Items, and new Horadric mechanics introduced in Season 9 - especially the Spiritborn class and Nightmare Dungeon affixes.
