In Goetic demonology, Amdusias is a Grand Duke of Hell. His appearance is said to be that of a man with claws instead of feet and hands, the head of a unicorn, and a trumpet, or either just a unicorn that can change into a man at request. He is associated with thunder, has a boisterous voice. Some sources say he can give concerts when commanded, and although they will be heard, instruments are never seen. He can also make trees bend at will.
