Playing a Hammerdin is relatively beginner friendly, and the combination of its clear speed and high magic find potential makes it one of the best, if not the best magic finding characters. It is capable of solo playing at player 8 difficulty, has very quick movement speed by teleport, and is a viable ladder starter as budget gearing options are available.
The build is overpowered to say the least. In addition, it deals 150% damage to Undead monsters. For attacking, it uses the Blessed Hammer skill with Concentration Aura, dealing up to 16k magic damage per hammer. It excels at monster farming, magic finding, has great survivability and is Hardcore viable.
The Hammerdin is amongst the most popular and efficient builds in the entire game.
