Custom Blood Magic: Ritual

The demons called Asuras oppose the gods themselves. Indian blood magicians seldom deal with such powerful spirits. As asuras in flesh themselves, however, they sometimes — in fits of hubris — believe that they possess a right to treat with their powerful cousins. Asuras (Sanskrit: असुर) are a class of divine beings or power-seeking deities related to the more benevolent Devas (also known as Suras) in Hindu mythology.

Asuras are sometimes considered nature spirits. They battle constantly with the devas. Asuras are described in Indian texts as powerful superhuman demigods with good or bad qualities. The good Asuras are called Adityas and are led by Varuna, while the malevolent ones are called Danavas and are led by Vritra. In the earliest layer of Vedic texts Agni, Indra and other gods are also called Asuras, in the sense of them being "lords" of their respective domains, knowledge and abilities. In later Vedic and post-Vedic texts, the benevolent gods are called Devas, while malevolent Asuras compete against these Devas and are considered "enemy of the gods".

A master Sadhu can prepare the proper materials and perform this ritual to summon one of the mighty Asuras to their service for an evening.  The Sadhu gather rituals components dedicated to the particular Asura they are looking to summon and command; he then sacrifices them into a dedicated fire along with some of his blood.  If done correctly the Asura will manifest and offer his service to the Sadhu for one task.

System: This ritual costs one blood trait to enact.  Once summoned the Asura will obey one command given to it by the caster before returning to its native realm.  This task must be able to be accomplished in one night or the Asura will simply vanish.  If they wish for the Asura to attack another creature the caster must also defeat the Asura in a contested Mental challenge retested with occult.  Asura are built using the stats for Pit Lords in Laws of the Night: Sabbat Guide page 108.  Note these creatures are not Demons.  Rather they are Spirit Like entities but also separate from them native to India and other places of Hindi, Buddhist, or Jani faith.

Summon Lamashtu (intermediate Abyss Mysticism Ritual)
In Mesopotamian mythology, Lamashtu was a female demon, monster, malevolent goddess or demigoddess who menaced women during childbirth and, if possible, kidnapped their children while they were breastfeeding. She would gnaw on their bones and suck their blood, as well as being charged with a number of other evil deeds. She was a daughter of the Sky God Anu.

Lamashtu is depicted as a mythological hybrid, with a hairy body, a lioness' head with donkey's teeth and ears, long fingers and fingernails, and the feet of a bird with sharp talons. She is often shown standing or kneeling on a donkey, nursing a pig and a dog, and holding snakes. She thus bears some functions and resemblance to the Mesopotamian demon Lilith.
Among the Abyss the Lamashtu are the servants of Ereshkigal.  They are her personal creatures of the Abyss.  The Priestesses of Ereshkigal learn to summon these creatures and command them for a time.  The Abyss Mystic speaks in the ancient forgotten Sumerian tongue and evokes their loyalty to Ereshkigal and using her name to command them. 

System: This ritual costs 1 Blood trait to cast.  Once summoned the Lamashtu will perform 1 task.  After either the task is performed the Lamashtu will depart.  Should stats for a Lamashtu be needed use the Demon creation rules from Laws of the Night Sabbat Guide page 108 using the stats for Fiends.  The Lamashtu are not demons. Rather they are Abyss Spirits entities but are not vulnerable to the power Spirit Manipulation.

Side Effect:  For a month after the Lamashtu has been summoned the caster must spend 1 additional blood trait to awaken for the evening.

Yakshas seem more like nature spirits. They generally look human, and several heroes married female yakshinis, but they too can change their form and cast illusions, as well as command natural phenomena such as trees and water.

A Yaksha is a nature spirit who are benevolent, sometimes mischievous custodians of treasures. Left: Yaksi, Right: Yaksa

Yaksha (Sanskrit: यक्ष yakṣa, Tamil: யகன் yakan, இயக்கன் iyakan, Odia: ଯକ୍ଷ jôkhyô, Pali: yakkha) are a broad class of nature-spirits, usually benevolent, but sometimes mischievous and sexually aggressive or capricious caretakers of the natural treasures hidden in the earth and tree roots.[3] They appear in Hindu, Jain and Buddhist texts, as well as ancient and medieval era temples of South Asia and Southeast Asia as guardian deities. The feminine form of the word is yakṣī or Yakshini (yakṣiṇī).

In Hindu, Jain, and Buddhist texts, the yakṣa has a dual personality. On the one hand, a yakṣa may be an inoffensive nature-fairy, associated with woods and mountains; but there is also a darker version of the yakṣa, which is a kind of ghost (bhuta) that haunts the wilderness and waylays and devours travelers, similar to the rakṣasas.

The Sadhu collects a rare collection of herbs and spices offering them in a sacrificial fire mixed with their own blood to summon a Yakshas.  Once summoned the creature will answer one question that it could reasonably know or play a trick one person they desire.

System: This ritual costs 1 Blood trait to cast.  Once summoned the Yakshas will either perform 1 trick on a target (in which case they will need a sympathetic link to the person) or answer 1 question the Sadhu desires.  The Yaksha may not know the answer to the desired question but will try its best to do so before departing.  Yaksha should only be able to answer a question hey would reasonably be able to know the answer to considering their spirit like status.  After either the trick is performed or the question answered the Yaksha will depart.  Should stats for a Yaksha be needed use the Demon creation rules from Laws of the Night Sabbat Guide page 108 using the stats for Fiends.  The Yaksha are not demons. Rather they are Spirit Like entities but also separate from them native to India and other places of Hindi, Buddhist, or Jani faith.

The known final mastery of the Inscription Ritual.  Its most potent form allows the Thuamturge to inscribe their most powerful rituals they may know. This generally requires the equivalent of a full page of paper. A reader can then unlock the power of that ritual by reading the inscription and following its instructions. The scribe uses his blood as a base for the ink, and his vitae’s power remains in the mixture to help fuel the ritual. An inscribed ritual is in imperfect form - it cannot be used to learn Thaumaturgy. It’s a simplified set of instructions, with the scribe’s vitae empowering the rite so that it overcomes any omissions or sloppiness on the part of the practitioner.

System: A thaumaturge who knows the techniques of Supreme Inscription can write an abbreviated form for any fifth-level ritual that he knows, at a cost of four blood points. Anyone who can read the language may then use the ritual notes later. Actually casting the ritual from the notes requires the use of the usual components and time, as well as the standard Mental Challenge, but the caster need not have any knowledge of Thaumaturgy. Once an inscription is complete, the power of the writer’s vitae is trapped in the object; his maximum blood pool is effectively reduced by three until the inscription is used. After use, the inscription dries into a fine, illegible ash, withal1 the power expelled from the vitae-based ink. The scribe can use the scroll himself (which is rather pointless) or give it to someone else. To prevent an inscription from reaching the wrong subject, many scribes also use Encrypt Missive (Blood Magic: Secrets of Thaumaturgy, p. 87) with this ritual.

It is known that the blood powering Inscription can be used for links of Sympathy and Identity an incautious Tremere could find his blood in the hands of an enemy who can use it against him.

A Storyteller must be present for you to use Inscription. You give your Blood Trait cards to the Storyteller, who should make a special mark on your sheet (placing an “I” over each used Blood Trait circle is a good idea). Place your Inscription upon an item card, with a note of the ritual and your character’s name (so that the Storytellers can tell who wrote it when it’s used up).

Reagents:
Drop of Hearts Blood of the Lichter Priest, 1 Lethal unavoidable and can't be tested down.
Removal of a Mortal Organ of choice
Description:
There are many who embody a very large portion of the everyday life of Followers of Set, a mortal's failing body presents noteable concerns for a Lichter Priest tending their various cults over the decades. Natural death may be an opportunity for study, but there are those within the flock who have a greater purpose, plans, or simply to deny the Aeons one of their flock's bodies into failure. Through continued understanding of Going Forth by Night, the Lichter Priest can remove a desired organ (failing or not), and through ritual, prayer and a single drop of their own hearts blood - their faith commands the magic within the mortal’s body to grow a replacement organ. The new organ fully grows while the mortal slumbers over the course of a few days and any ailments caused by the removed organ immediately heal, so long as the ritual is successfully performed. Secondary illnesses that occurred as a result of the illness remain, however without the underlying cause of the offending organ, the mortal's body is able to begin to heal naturally. This is very obviously a form of “Faith Healing”, but due to the surgical nature is not likely to be performed in a tent revival camp. Equally however it could be performed on an otherwise healthy mortal, assuming the ritual is successful there wouldn’t seem to be any side effects of having done so. The mortal then has relatively unique “post-op” care that focuses heavily on prayer. Through faith they were healed, and only by sustaining that faith is the illness kept at bay.
Casting:
The Lector Priest uses this ritual to replace a failing organ in a mortal subject. The subject is then healed over the course of a few days of the ailment to that organ (i.e., cancer, liver failure, or even spinal damage causing paralysis.). In exchange, the subject must undergo a recurring act to demonstrate their devotion to the same Faith as the Lector Priest. These acts must be performed regularly and frequently as well as observe every festival of the faith. If the subject fails to perform these acts they begin to suffer the effects of their original affliction and the magical organ begins deteriorating. The victim loses one physical trait per week (should the lose all their physical traits they die) or begin performing their regular and frequent dedications of faith, at which time they recover at a rate of one trait per week until fully restored.
Success or Failure:
If the ritual challenge is successful, the mortal awakens several days later fully healed of both the organ’s removal and any offending ailment, as well as the methods which removed it.

If the ritual challenge is not successful, the mortal may yet still live so long as an organ removed is one the mortal can live without. If an otherwise “fatal” organ was used, the mortal dies instantly. As the ritual process involves the act of removing the organ, casting the ritual again on the same organ has no effect. The organ must be replaced in other methods.
