With every blow from the hammer that struck, a crater was formed and lightning struck the ground. Fingolfin managed to evade these blows, and gave Morgoth seven great wounds, which caused enough of Morgoth's blood to pour out to fill the pits. However, Fingolfin eventually stumbled into one of the craters and was pinned by the Dark Lord's left foot. And as Morgoth made to kill Fingolfin, the High King made one last strike, forever crippling the Dark Lord's foot, forcing him to walk with a limp. Morgoth had poured much of his power into Arda, taking a physical form, unlike the other Valar. And so he was made vulnerable in the process and became less powerful in self than he once was.
During the Third Age, Sauron, Morgoth's trusted servant and his successor as the Dark Lord, perhaps in homage to the Hammer of the Underworld, gave the name Grond to an enormous battering ram forged in Mordor to smash open the gates of Minas Tirith.
