Amduscias in the Pseudomonarchia Daemonum
Weir (1583) describes Amduscias as a great duke who commands 29 legions. He appears as a unicorn but will transform into human form if commanded to do so. His powers include causing musical instruments to play unseen, bending trees, and bringing familiars.
Amduscias a great and a strong duke, he commeth foorth as an unicorne, when he standeth before his maister in humane shape, being commanded, he easilie bringeth to passe, that trumpets and all musicall instruments may be heard and not seene, and also that trees shall bend and incline, according to the conjurors will, he is excellent among familiars, and hath nine and twentie legions. 1Weyer, Johann. “Amduscias.” Pseudomonarchia Daemonum. 1583.

Amduscias in the Dictionaire Infernal
According to Collin de Plancy (1863), Amduscias is a Grand Duke who governs twenty-nine legions. He appears as a unicorn but can also appear in human form if asked. He can be commanded to give musical concerts where trumpets and other musical instruments are only heard, not seen. He can also command trees to bend.2Collin De Plancy, Jacques Auguste Simon. “Aguares.” Dictionaire Infernal. Paris: Henri Plon, Imprimeur-Editeur, 1863. 24. Internet Archive.
Amdusias in the Goetia
S. L. MacGregor Mathers’ description of Amdusias is virtually identical to Weir’s description. Both include the note about giving good familiars, whereas de Plancy does not.
The Sixty-seventh Spirit is Amdusias, or Amdukias. He is a Duke Great and Strong, appearing at first like a Unicorn, but at the request of the Exorcist he standeth before him in Human Shape, causing Trumpets, and all manner of Musical Instruments to be heard, but not soon or immediately. Also he can cause Trees to bend and incline according to the Exorcist’s Will. He giveth Excellent Familiars. He governeth 29 Legions of Spirits. And his Seal is this, etc.3Mathers, S. L.
