When it comes to the best Paladin build in Diablo II: Resurrected, it's hard not to suggest players to go for the Hammerdin route.
One of the strongest configurations in the game, let alone the class, the Hammerdin, or Hammer Paladin, build turns players into defensive stalwarts buffed massively by Vigor, Blessed Aim and Concentration that also smite their enemies with Blessed Hammer. Here is how to assemble the best Paladin build in Diablo II: Resurrected.
Best Paladin Build in Diablo II: Resurrected
Starting off with the stats for this Paladin build, you'll want to put enough Strength to use the equipment you want, and first use your Holy Shield Skill and then assign points into Dexterity until you reach the 75% Cap to acquire Max Block. After that, simply spend all your remaining points in Vitality as it will often be the deciding factor in whether or not you survive a fight on the harder difficulties — even more so than armor or other resistances. It's generally a waste for Paladins to put points into Energy as you can always refill your mana using potions.
For the Combat Skills tree, you'll want to put one point into Smite, Charge, and Holy Bolt, then invest 20 points each into Blessed Hammer and Holy Shield. For Offensive Auras, put one into Might, and 20 points each into Blessed Aim and Concentration. Lastly, with the Defensive Auras skill tree, put one point into Prayer, Defiance and Cleansing, and 20 into Vigor.
For the gear, there are a lot of good options, but mainly prioritize those with Plus Skills, Faster Cast Rate, Resistances, % Damage Reduction and Magic Find.
Lastly, for the mercenary, go for the Act 2 Nightmare Might Mercenary for a great increase in damage, or the Act 2 Nightmare Holy Freeze Mercenary for the extra crowd control.
Overall, the Hammerdin Paladin is a pretty straightforward build that focuses on Blessed Hammer to tear through just about every monster in a game where there aren't that many magic immunities. On top of that, it's very easy to achieve max block with this build.
