Blessed Hammer

Blessed Hammer is a Paladin Skill in Diablo II.

Lore
''The Visions of Akarat tell of a hopeless battle. Legions of the undead had laid siege to a small convent of nuns who were the keepers of a sacred relic, the Hammer of Ghrab Thaar. Suspended over a fiery chasm within the convent, the sisters knew the Hammer to be a powerful vessel of the Light and vowed never to allow it to fall into the hands of evil. With no weapons of their own, and no one to defend them, the nuns sacrificed themselves to destroy the hammer. Rather than let the undead despoil the church and the relic, they took the hammer and plunged themselves into the fiery chasm. At that moment, a powerful force of Light washed over the undead legion, striking them down where they stood. Since that time a well-trained Paladin is able to tap the remnants of this released energy, whirling a magical hammer to strike down his adversaries, especially the forces of the walking dead. ''

General Information
This skill sends out a piercing glowing Hammer that spirals outwards from the front of the caster upon activation. The Hammer spins clockwise around the place it was cast, making a wider and wider arc until disappearing when it reaches its maximum range. Blessed Hammer has the ability to damage multiple enemies if it hits them. The Paladin may summon as many Hammers at a time as he can with Mana and Cast Rate.
 * The Undead take additional damage.
 * Receives bonuses from Concentration (50% of the damage increase).
 * Mana Steal and Life Steal bonuses from items and weapons do not apply to Blessed Hammer.

This spell is the signature move of the infamous Hammerdin build. Synergies increase its damage potential, reaching well above the 10,000 damage range. Added to the fact that not many monsters are immune to Magic, it was easy to spam the skill repeatedly and fill an entire room with Hammers in seconds, dealing tons of damage to anything inside. The build's high damage output and powerful Area of Effect ability causes Hammerdins to be feared in PvP servers.

Development
Since patch 1.13, it no longer ignores Demon and Undead immunities.
