King Amdusias has twenty-nine legions of demons and spirits under his command and has the rank of "Great King". He is depicted as a human with claws instead of hands and feet, the head of a unicorn, and a trumpet to symbolize his powerful voice.
Amdusias is associated with thunder and it has been said that his voice is heard during storms. In other sources, he is accompanied by the sound of trumpets when he comes and will give concerts if commanded, but while all his types of musical instruments can be heard, they cannot be seen. He is regarded as being the demon in charge of the cacophonous music that is played in Hell and can make trees bend at will.
In Castlevania: Symphony of the Night he has a puffy red-furred mane and wears dark-colored armor, whereas in Castlevania: Curse of Darkness his torso is exposed and holds a magic book on his hand with which he attacks by summoning bizarre tornadoes from ripped out pages.
In the North American version of Symphony of the Night he is called Hellfire Beast, while in the original Japanese version he is called Amduscias. He only appears in one room in the Catacombs.
He is described as "a horse-like monster known as the Artist of Hell". He attacks by conjuring tornadoes of ripped out pages from a book. He drops the rarest combining material in the game, the Angel Halo.
Amduscias may seem hard to kill at first, but there's an easy way to deal with him: just jump over him while he dashes and lure him into casting his lightning bolt attack. Quickly get behind him and cast 1,000 Blades. However, be aware of casting this dual crush only when he is in the middle of his lighting attack and not right away as one enters the room; he has notably high HP and will most likely withstand the barrage of blades long enough for him to cast it, which will most certainly mean an almost instant death to the player as they will get stun-locked while receiving powerful and continuous electric shocks that will deplete all their HP, even if they are at a very high level. On occasion, this lightning attack can cause Curse status.
