Hera felt very guilty and gave him loads of supplies, materials, tools, and helpers for his workshop. Hephaestus made the best weapons, jewelry, and armor. Some of his greatest creations ever were the silver bows and arrows of Artemis and Apollo as well as Apollo’s golden chariot. He also made the shield of Achilles, Athena's spear, and Hercules' breastplate. In addition to this he made the scepter of Zeus and the battle armor of the Olympian armies. He also made all of the gods and goddesses palaces and their unbreakable locks. On top of all this, Hephaestus was and is still credited with the invention of the three-legged stool and the world’s first robots. Hephaestus helpers included a complete set of life size golden maids who helped around the house.
