In Diablo 4 Season 13, players are embracing the Paladin class, particularly the Hammerdin build, which offers a robust and efficient way to level up. This build emphasizes the Blessed Hammer ability, allowing players to deal significant damage while remaining tanky through Defiance Aura and Fanaticism Aura. The build is straightforward, requiring minimal specific Legendary Aspects, making it accessible for new players. Key skills to prioritize include Holy Bolt for faith generation, and Condemn for added damage. Players should also consider using Varyana as their primary mercenary for added damage and healing, alongside Aldkin for crowd control. While leveling, the Practiced Technique set provides essential bonuses like increased attack and movement speed. For transitioning into endgame content, items like Herald's Morningstar and various Legendary Aspects are recommended to maximize the build's potential.
