Firbolgs are a race of humanoid giant-kin, as such, they could measure over 10 feet (3 meters) tall. They prefer spending their days in quiet, harmonious solitude with the woods as the forests were sacred to them and symbolized the heart of the earth and the adaptability of life. They saw themselves as the forests' caretakers. When provoked firbolgs demonstrate formidable skills with weapons and druidic magic. They are said to be resistant to magic, sense the presence of magical auras innately and also to have the power to change their physical appearance, including making themselves larger or smaller or turn invisible.
