Obsidian Leggings are part of the Obsidian Armor set. They are the 3rd strongest pair of Leg armor and give 3 armor points. The Obsidian Leggings, like the rest of the Obsidian items, appear different than their counterparts. For Obsidian Armor, the outfit appears to be made of layers of material. This is not far from the truth, as the Obsidian Armor is crafted with Obsidian Slate.
