Mountain

Mountain spirits tend to solemn and patient. They are slow to judge and slower to act, but once they are determined, they are decisive and powerful in their response. They prefer to drive intruders away, reserving their might for only the direst of threats.

When it manifests, a mountain spirit creates a massive titan of earth and stone from its host. If angered, this form is a powerful war machine.
