Crom Faeyr

Crom Faeyr is an enchanted war hammer +5, which means it's no longer affected by spells such as Absolute Immunity and Improved Mantle. It raises the strength of the user to 25. The hammer is able to inflict 2D4 +3 + 5 electrical points of damage and has +5 bonus to thaco and a speed factor of 1. This warhammer has the ability to instantly slay Stone Golems, Clay Golems, Trolls and Ettins when hitting them. When used in combat, this hammer can easily deal 20-30 physical points of damage and with criticla hits, it can hit between 50-65 (electrical damage not included).

This item appears Baldur's Gate II: Shadows of Amn and it's the most powerful war hammer. The hammer can be obtained if the Hammer of Thunderbolts, Hands of Takkok, Girdle of Frost Giant Strength and a Crom Faeyr Scroll are combined by Cromwell for 10,000.

In-game description
"This is the true name that the dwarven weaponsmith, Silverblade, gave to the weapon he intended to create for his son. Alas, his son died before the weapon was ever completed, but here it stands complete... forged from the combined magic of the original hammer with the Gauntlets of Ogre Power and a Girdle of Frost Giant Strength. Crom Faeyr gifts its users with all the powers of the original Hammer of Thunderbolts, in addition to enormous strength and the ability to kill golems, ettins and trolls in one blow."
