A Hammerdin is a Paladin build involving the maxed-out use of the Blessed Hammer skill. This build is favored due to the extraordinary damage of the Blessed Hammer, coupled with its synergies, Vigor and Blessed Aim. Concentration Aura also adds damage. It is the most played character build in Diablo II, as Hammerdins dealing 20,000 damage per hammer are not uncommon. However, it is one of the most expensive builds to successfully create, as there are so many Hammerdins out there. A Hammerdin will use his Enigma Rune Word to teleport next to large mobs of enemy, and then hit them with multiple hammers. Many saw this build as being overpowered, and so 1.13 attempted to balance this by removing Blessed Hammer's Demon and Undead immunity bypassing. However, this only slowed Hammerdin Baal runs
