Dwomutsiqsa

Dwomutsiqsa (meaning "Summon Demon" in Sith) was an ancient Sith incantation that summoned a manifestation of the dark side known as the Smoke Demon.

Description
The ancient Sith ritual of Dwomutsiqsa was written on scrolls. Through this incantation, the caster would concentrate the air and the energy around them to conjure a dreambeast known as the Smoke demon. This creature had no true form, and it would assumed the shape of its victim's worst fear. When read aloud by an imprudent user, this spell released malevolence as a safeguard against them who wished to unravel the mystery of the scrolls.

How to Use it.
In order for one to conjure and use such an incantation the caster must be powerful, and protected quite well. The afflicted must have either a weak mind, or an unshielded mind, depending on how powerful the caster is. The caster should prepare the usage of the incantation by channeling darkside energies, and have a very strong knowledge and usage of the High Sith language. Once the caster has fully channeled the darkside energies, he or she must chant the following lines:"Woyunoks hadzuska koshûjontû.""Dranas nairi diâ nuniji wos ki zûtaikima,""qutzi sosûti anas ani kayti arsia""ki na j'us kiha shanwi""kaj is ki driyiwori"These lines should be repeated about five times, as more and more power is channeled into each and every line, and eventually the Dwomutsiqsa, should appear and manifest it's self into the afflicted's worst fear, and surely will kill them. However, should the incantation's chanting stop prematurely or insufficient power be implemented into the incantation, it may not properly summon or be strong enough to manifest it's self and harm the afflected. Though, this could prove useful for torture and interrogations, by subjecting them to a non-lethal variation of their worst fear.
