Who brings Achilles a new armor and shield?

In Homer's "Iliad," Achilles receives new armor and a shield from Hephaestus, the god of fire and craftsmanship. After the death of his close friend Patroclus, Achilles seeks vengeance against Hector and requires new armor to return to battle. The goddess Thetis, Achilles' mother, appeals to Hephaestus, who then forges the magnificent armor and shield, adorned with intricate designs that symbolize his prowess and fate in war.
