Huge humanoid creatures, rumored to be a mix of man and giant, Firbolg are wood-dwelling and are as attuned to nature as Celts, whom they often befriend. Because of their size and strength combined with their empathic connection to the forest, they often make excellent fighters and healers.
Classes available to Firbolgs
