Furio is tall and well-groomed, with an aristocratic plumpness to his frame that has yet to disappear during his year of exile. Unlike most tieflings, he is clearly used to wearing his diabolic heritage as a mark of distinction and he continues to show them off proudly.  His curling horns are oiled and polished, his cloven hooves neatly trimmed, and his writhing, ratlike tail usually bears a silver armband or other decoration.

Though Furio uses magic to keep his clothes and body scrupulously clean, his scent carries a slightly unpleasant tinge of sulfur or rotten eggs.  It's unclear whether this smell is related to his infernal origins, the spell components he carries, or if he applies it intentionally as some sort of intimidation tactic.
