Obsidian Legs

The KotHaar do not die as we do. There is no afterlife for them, just silence. They are reduced to fragments of obsidian, crushed down and down with the weight of their souls. Once returned to the Elder Kiln the KotHaar will live again, it just may take some time. Fortunately, time is irrelevant to the KotHaar and they are content to simply wait out the aeons until their time comes again. So, in a way, you do them a favour by wearing this obsidian armour, as it gives them a chance to see the world as they wait.

The joints and pivot points in this leg armour takes a little time to adjust to. They were originally moved by pneumatic systems of magma and rock, rather than the fleshy nonsense that comprises the human form.
